     // FIXME: We need to find a way to set up overflow properly. Our flow thread hasn't gotten a layout
     // yet, so we can't look to it for correct information. It's possible we could wait until after the RenderFlowThread
     // gets a layout, and then try to propagate overflow information back to the region, and then mark for a second layout.
     // That second layout would then be able to use the information from the RenderFlowThread to set up overflow.
     //
     // The big problem though is that overflow needs to be region-specific. We can't simply use the RenderFlowThread's global
     // overflow values, since then we'd always think any narrow region had huge overflow (all the way to the width of the
     // RenderFlowThread itself).

Fix the naming typo while you're at it:
paintInvalidationOfFlowThreadContentRectangle

Done.
