In Safari and Firefox, the "tab" key does the same thing.
In Chrome, the "tab" key does the same thing if {nav Preferences > Web Content > "Pressing Tab highlights..."} is disabled.

Summary:
This fix further addresses T10229. The problem and solution are the same:
- If the DOM is mutated during a touch, it never registers as a 'click' so the tapped button does not activate.
- This was partially addressed in D15136, which covered taps on code lines in a Differential view.
- Tapping on some buttons, like "Reply" or "Hide Comment" still caused the problem by showing a tooltip.
- There are probably similar buttons elsewhere, other than in Differential, exhibiting the same 'needs multiple taps to work' behaviour.
- The testing in the iOS simulator performed for D15136 did not reveal that the problem with "Hide comment" and such remained because the small device size used for testing triggered the `!= 'desktop'` path for tooltips.
To fix it:
- Don't show tooltips for touch events. You can't 'hover' with a finger (with today's tech) so that UI paradigm doesn't apply.
- Show the tooltips for regular mouse events, even if they are on the same device. Some devices have both touch and a mouse.
- No longer try to rely on a distinction between 'desktop' and 'mobile' devices. Mobile devices like the iPad Pro are essentially desktop like, and as mentioned above, a single device could be both touch and mouse enabled. It's not about the nature of the device, it's about the nature of the interaction.
Test Plan:
- Tapped "Hide Comment", "Reply" on an iPad Pro running iOS 9.2 and got single touch responses with no tooltips.
- Tried the same on an iPhone 6 running iOS 9.2.
- Hovered over the same on a regular desktop in Safari and saw tooltips. Clicked and saw regular reactions.

Summary:
Ref T4900. The root problem is that dragging stuff near the bottom of the board can cause jittery, jumpy behaviors.
Internal scrolling has changed the nature of this problem. Previously, the height of the board itself would jump around, but it's now fixed so the height of columns jumps around instead.
We could take the same approach and add a chunk to the bottom of each column when a drag starts, but this is really distracting visually since it's obvious to the user.
Instead, treat columns as infinitely tall (so dragging beneath them still counts as dragging to the bottom position).
Test Plan:
- View a board with a column taller than the screen (has a scrollbar).
- Drag a card to near the bottom position.
- Move the mouse down a little bit at a time, continuing toward the bottom of the page.
- Before patch: at some point, UI flips out and starts rapidly adding, scrolling, and removing the ghost.
- After patch: sensible behavior, ghost is in bottom position for all cursor locations.
Also works for dragging to the top.

Summary:
Ref T5240. Currently, when dragging nodes, we leave them where they are in the document and apply "position: relative;" so we can move them around on screen.
- Pros: All the CSS still works.
- Cons: Can't drag them outside the nearest containing element with "overflow: hidden;", many subtle positioning bugs with scrollable containers.
Instead, this diff leaves the thing we're dragging exactly where it is, clones it, and drags the clone instead.
- Pros: You can drag it anywhere. Seems to fix all the scrolling container problems.
- Cons: CSS which depends on a container class no longer works.
The CSS thing is bad, but doesn't seem too unreasonable to fix. Basically, we just need to put some `phui-this-is-a-workboard-card` class on the cards, and use that to style them instead of `phui-workboard-view`, and then do something similar for draggable lists.
Although we no longer need to drag cards to tabs with the current design, I think there's a reasonable chance we'll revisit that later. The current design also calls for scrollable columns, but there would be no way to drag cards outside of their current column with the current approach.
NOTE: This does not attempt to fix the CSS, so dragging is pretty rough, since the "clone" loses a number of container classes and thus a number of rules. I'll clean up the CSS in the next change.
Test Plan:
- Dragged stuff around on task lists, workboards, and sort lists (e.g., pinned applications) in Safari, Firefox and Chrome.

Summary:
Fixes T10229. Broadly:
- When the user hovers over a line number or inline comment, we update the yellow reticle to highlight the relevant lines. Specifically, this is in response to a `mouseover` event.
- On touch devices, touches fire `mouseover` and if you mutate the DOM inside the event, the device aborts the touch.
To remedy this:
- Distingiush between mouse-originated and touch-originated cursor events.
- We do this, roughly, by setting a flag when we see "touchstart", and clearing it when we see the second copy of any unique cursor event.
- This method is complex, but should be robust to any implementation differences between devices (for example, it will work no matter which order the events are fired in).
- This method should also produce the correct results on weird devices that have both mouse-devices and touch-devices available for cursor input.
- When we see a touch-originated `mouseover` or `mouseout`, don't mutate the DOM.
- Put an extra DOM mutation into the `click` event to improve highlighting behavior on touch devices.
Test Plan:
- In iOS Simulator (4s, iOS 9.2), clicked various inline actions ("Reply", "Hide", "Done", "Cancel", line numbers, etc). Got responses after a single touch.
- Verified hover + click behavior on a desktop.
- Logged and examined a bunch of events as a general sanity check.
