As of a local m-c build from Oct 30, these display items are still doing fallback on gmail:

AltFeedback
Background
BoxShadowOuter
ButtonBorderBackground
ButtonForeground
FieldSetBorder
ThemedBackground

(plus event regions, but I have a patch to stop trying to create WR commands for that)

The STR I used are:
- build firefox with logging to record all the fallback items [1] in the content process
- log in to gmail (enterprise gmail, using my @mozilla.com email address)
- set the browser preferences to "restore previous tabs and windows on start"
- restart the browser with WR enabled and pipe log to a file
- once gmail loads fully close browser
- grep log file for fallbacks

[1] any item where http://searchfox.org/mozilla-central/rev/1c4901d060e3953e41088c038b62a0c026c1e1fb/gfx/layers/wr/WebRenderCommandBuilder.cpp#226 returns false

We do well enough for now.
