> We don't have a repro we can share yet, but I know the offending line. When RenderSVGRoot::negotiateSizeWithHostDocumentIfNeeded calls ownerRenderer->setNeedsLayoutPrefWidthsRecalc(), it sets us up for this. We get called to paint before that layout has occurred which triggers this bug. Commenting this out makes the assertions go away.

That's what I guessed as well. I believe this is related to other flakiness in that area, that is guilty for some svg/zoom/page/zoom-object* tests that have recently been disabled. Let's see.

It would be great if we had a simple reduction though!
