I skipped it on Qt - https://trac.webkit.org/changeset/127110
Please uskip with the proper fix. (but see https://bugs.webkit.org/show_bug.cgi?id=95432 before unskipping.)
Florin Malita
Just a note: I don't think this was introduced with the 126993 patch (as it only touches the transformation matrix), but it's something that got exposed by the new test.
Csaba Osztrogonác
The bug is still valid now.
