1946479 - [meta] per push permanent web-platform-tests reftest failures due to antialiasing (?) on Windows 24H2

Status: NEW

(Core :: Web Painting, defect)

Description

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

With web-platform-tests reftests running on Windows 24H2, code sheriffs have observed permanent test failures per push, likely cause by the individual set of test manifest scheduled for these pushes.
