Details

This causes incorrect invalidation with DLBI (bug 539356), since we don't necessarily redraw all the pixels that are affected by this display item. I've temporarily expanded the size of nsMathMLCharForeground::GetBounds() to avoid this.
Jonathan, can you look into this? It shouldn't be that hard to fix so that MathML frames get the correct overflow area.
