Re: [css-flexbox] Abspos change web compat risk

FWIW, I'm planning on focusing on the Firefox version of this bug in the
next month or so.

(To be fair, that's approximately the state I've been in for quite a
while now, and other priorities have just been taking my attention.  But
I think it's really going to happen now.)

We continue to see bugs incoming due to this inconsistency. If anyone here that represents a browser vendor could please encourage their flex developers to make this change so that we can keep this capability for abspos flex items. I fear that if Blink/Gecko/Webkit wait too much longer the web compat pain will be too high and may require a specification change and create an inconsistent model between that of flex & grid.
