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.)

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.
