I will test it to make sure that it doesn't miss reordering in some cases that are needed, but I suspect it will be fine. Btw, since this is a regression caused by [JDK-8252373](https://bugs.openjdk.org/browse/JDK-8252373), and I backported that fix to jfx25u, this regression fix should also be backported once integrated into mainline. ------------- PR Comment: https://git.openjdk.org/jfx/pull/1985#issuecomment-3576964314 PR Comment: https://git.openjdk.org/jfx/pull/1985#issuecomment-3576969495
