Reviewed by Alan Baradlay.
We can get stuck in `m_accumulatedRepaintRegion` mode when hitting the `if
(!iframeOwnerRenderer)`
clause in `RenderView::flushAccumulatedRepaintRegion()`, which breaks all
future repaints in the
iframe. This happens when the iframe starts as `display:none`, for example.
Fix by ensuring that when we early return here, we also clear
`m_accumulatedRepaintRegion`.
