@lukasza -- Could you please look into the issue, kindly re-assign if this is not related to your changes.
Thank You.

fmalita@, could you PTAL as a core/layout owner?

Odd: we're clearly under blink::FrameView::PerformLayout(), so I don't understand why the root_.GetDocument().View()->IsInPerformLayout() check would trigger.

Based on the stats graph, it looks like a windows-only flake.

Punting to layout-master eae@ for triage.
