Short version: we hit a situation where we have a minimal display port, then SetZeroMarginDisplayPortOnAsyncScrollableAncestors clears the minimal display port to install a zero margin display port. Once the minimal display port is cleared we get a random (errant) repaint request from apz which sets a full display port (it doesn't want a display port, it just wants to sync content and apz).
