Fix current paint invalidation issues using the tree walker in PaintPropertyTreeBuilder which can handle special cases of paint ordering correctly. Enable it before slimming paint v2 to make it stable earlier.
I'm closing this bug because we have addressed all issues as planned.
Migration to PrePaintTreeWalk for spv1 is still an option. Will create a new issue for it when needed.
