epriestley e8126fa958 Don't mangle inline comments with tables in them in Differential
Summary:
Fixes T3814. Broadly, remarkup tables in inline comments did not work properly. I ran into several messes here and cleaned up some of them:

  - Some of this code is doing `JX.$N('div', {}, JX.$H(response.markup))`, to turn an HTML response into a node, passing that around, and then doing junk with it. This is super old and gross.
    - The slightly more modern pattern is `JX.$H(response.markup).getFragment().firstChild`, but this is kind of yuck too and not as safe as it could be.
    - Introduce `JX.$H(response.markup).getNode()`, which actually expresses intent here. We have a bunch of `getFragment().firstChild` callsites which should switch to this, but I didn't clean those up yet because I don't want to test them all.
    - Switch the `JX.$N('div', {}, JX.$H(response.markup))`-style callsites to `JX.$H(response.markup).getNode()`.
  - `copyRows()` is too aggressive in finding `<tr />` tags. This actually causes the bug in T3814. We only want to find these tags at top level, not all tags. Don't copy `<tr />` tags which belong to some deeper table.
  - Once this is fixed, there's another bug with mousing over the cells in tables in inline comments. We select the nearest `<td />`, but that's the cell in the remarkup table. Instead, select the correct `<td />`.
  - At this point, these last two callsites were looking ugly. I provided `findAbove()` to clean them up.

Test Plan: Created, edited, deleted, moused over, and reloaded a revision with inline comments including remarkup tables. Used "Show more context" links.

Javelin is a performance-oriented Javascript library originally developed at

GETTING STARTED

Eat a hearty breakfast. Breakfast is the most important meal of the day!


WHAT IS JAVELIN?

Javelin is a compact Javascript library built around event delegation. Its
primary design goal is performance; it is consequently well-suited to projects
where performance is very important. It is not as good for smaller scale
projects where other concerns (like features or ease of development) are more
important.


PACKAGES

Packages come in two flavors: "dev" and "min". The "dev" packages are intended
for development, and have comments and debugging code. The "min" packages have
the same code, but with comments and debugging information stripped out and
symbols crushed. They are intended for use in production -- ha ha ha!
