Can you leave a comment here explaining why this can be the case? And maybe
early out before AppendDebugBorderQuad (or put a MissingTileBorderColor on it
instead or something)

If it's a workaround, can you leave a TODO pointing to a bug stating as such?

       return;
 
     gfx::Rect quad_content_rect = shared_quad_state->visible_quad_layer_rect;
