Other information

Chrome would like to implement these additions to the contain-intrinsic-size spec and is seeking Mozilla's position on these.

[dholbert]

In general the feature seems reasonable, but I'm a little concerned about the hand-waviness around "last remembered size". I filed w3c/csswg-drafts#6220 to get spec clarification there.

[cbiesinger]

FYI Blink is now shipping the longhands in canary (not the auto handling yet)

@dholbert just to check, are you happy with the latest version of the spec?

[dholbert]

Yes, the latest version of the spec looks reasonable to me (now that the above-mentioned "last remembered size" issue has been resolved). Thanks!
