These were originally lumped with the svg tests failing due to SP1 (https://bugs.webkit.org/show_bug.cgi?id=56617), but are probably due to something else.
I think Windows 10 or 11 might be supported but not Windows 7 anymore: Link - https://build.webkit.org/#/builders Is it something worth tracking or can this be marked as "RESOLVED INVALID"? Thanks!
Oh, we don't even have Windows WK2 bot so this is sort of irrelevant at least for now.
