Since I don't have a Windows platform to test one I can't narrow the regression range. However, I have made a few observations: 1. Looking at the commits in the range I believe https://commits.webkit.org/255406@main is the commit that may have introduced this regression as it modified the render element. But I am not 100% certain of this. 2. While this does appear to be a regression, these tests MIGHT just need Image rebaselines. If that's the case I will need assistance with this because I'm unfamiliar with the process to rebase images.

(In reply to EWS from comment #3) > Test gardening commit 255839@main (af55515371c8): > <https://commits.webkit.org/255839@main> > > Reviewed commits have been landed. Closing PR #5638 and removing active > labels. I have marked expectations for these tests as [ ImageOnlyFailure ] due to the negative impact on EWS.
