Summary:
Ref T4420. Fixes T3309. Two major UX issues here:
- When the user extends a query ("alin" -> "alinc"), we currently hide all the results, then show them again when the new results arrive. This makes the typeahead feel a bit flickery. Instead, show matching results, then add more results when everything arrives.
- When loading more results from ondemand sources, we currently do not give you any indication that things are loading. Instead:
- Show a loading GIF (this might need #design help, @chad).
- Slightly lighten the control border.
- I didn't want to do anything like actually add "loading" text because it would cause UI flicker in the 'extend a query' case and some other cases, but otherwise this design is totally made up.
Test Plan: Typed into tokenizers and extended queries, got a better-feeling UI.
