It should return the original function list with pixels where percents used to be, etc. 1827885 1 mrobinson 2022-01-04 02:22:30 -0800 I believe this issue can be closed and the comment in CSSComputedStyleDeclaration.cpp can be removed because the CSS Transforms Module Level 2 specification says: "A <transform-list> for the computed value is serialized to either one <matrix()> or one <matrix3d()> function by the following algorithm:" 1874588 2 nmouchtaris 2022-06-07 15:33:24 -0700 I think the spec you were looking at was out of date Martin. According to https://drafts.csswg.org/css-transforms/#serialization-of-transform-functions, we should be serializing the individual functions. This is related to our test failures in css/css-transforms/animation/transform-interpolation-inline-value.html. 1882997 3 mrobinson 2022-07-13 07:53:21 -0700 I've been investigating this a bit more and I confirmed that getComputedStyle(...).transform always returns `matrix()` or `matrix3d()` whereas div.style after running `commitStyles()` is returning the individual transform functions. In WebKit, `div.style` is returning `matrix()` and `matrix3d()` always after `commitStyles()`. I think the failure in css/css-transforms/animation/transform-interpolation-inline-value.html are probably an issue with `commitStyles()`. 1882999 4 mrobinson 2022-07-13 07:53:59 -0700 (In reply to Martin Robinson from comment #3) > I've been investigating this a bit more and I confirmed that > getComputedStyle(...).transform always returns `matrix()` or `matrix3d()` > whereas div.style after running `commitStyles()` is returning the individual > transform functions.

To clarify, div.style after running `commitStyles()` is returning the individual transform functions in Firefox and Chrome. 1898502 5 graouts 2022-09-14 11:29:59 -0700 This is also an issue with getKeyframes() always returning the matrix form. 1898503 6 graouts 2022-09-14 11:36:03 -0700 I think I'll take a crack at it. 1898720 7 graouts 2022-09-15 09:28:52 -0700 I've made good progress here, still something to polish off before I can file a patch. 1900333 8 graouts 2022-09-22 02:55:38 -0700 Pull request: https://github.com/WebKit/WebKit/pull/4591 1900371 9 graouts 2022-09-22 07:26:20 -0700 The fix for this will cause a slight WPT regression tracked by bug 245523. 1900397 10 ews-feeder 2022-09-22 10:47:26 -0700 Committed 254760@main (ae44d0ca68fa): <https://commits.webkit.org/254760@main> Reviewed commits have been landed.
