There is an r+ patch which didn't land and no activity in this bug for 2 weeks.
:mozilla, could you have a look please?
If you still have some work to do, you can add an action "Plan Changes" in Phabricator.
For more information, please visit BugBot documentation.

I'll pick this one up next week, thanks!

Is this implemented behind the pref layout.css.field-sizing.enabled? (Skimming through the code, it doesn't seem so.)

I've commandeered the revision, and I plan to wrap it behind the pref, but I won't get to those changes for a few weeks.

It's gated by virtue of the fact that field-sizing won't parse without that flag being enabled.
