Filing this bug to cover implementation of the "object-view-box" CSS property.

See also https://github.com/w3c/csswg-drafts/issues/7143 (and probably several other csswg-drafts issues) where this has been discussed, too.

Supporting view-box would align us with Safari and Chrome by passing the two WPTs where we presently don't align for the css/css-transforms/transform-box tests (cssbox-initial.html and svgbox-initial.html), so it might be worth prioritizing over the other features which Chrome doesn't yet support on the same tests.

I guess you were talking about Bug 1819464. This bug shouldn't be related to css transform.

Indeed that seems to be the case. My mistake, thanks for checking!
