Automatic update from web-platform-tests [Gap Decorations]: Disentangle resolved -width values from -style This CL decouples the resolved value of outline-width and column-rule-width from their corresponding *-style properties. The second part of the CSSWG resolution[1], stipulates that the resolved value for these properties should now be independent of the *-style. Most file changes in this CL involve updating tests to reflect this new behavior. To simplify reverting in the case of a web compat issue, a virtual test suite with the flag disabled and relevant tests as base has been set up. A subsequent CL will be put up to set up use counters to evaluate potential web compat risks associated with this change [1]: https://github.com/w3c/csswg-drafts/issues/11494#issuecomment-2675800489 Bug: 393631108 Change-Id: I241d253b14493f45dc6b143286bfa031261fac27 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/6909751 Reviewed-by: Kevin Babbitt <kbabbitt@microsoft.com> Commit-Queue: Sam Davis Omekara <samomekarajr@microsoft.com> Reviewed-by: Alison Maher <almaher@microsoft.com> Reviewed-by: Philip Rogers <pdr@chromium.org> Cr-Commit-Position: refs/heads/main@{#1516261} -- wpt-commits: 7f15bbaf0b6d43a99ba964e42649bc3878e9b819 wpt-pr: 54881
