Bug 1005405 - OverflowChangedTracker::Flush() no longer downgrades parent frames from CHILDREN_AND_PARENT_CHANGED to CHILDREN_CHANGED. r=dbaron, a=sledru

- When OverflowChangedTracker::Flush() coalesces multiple changes
  simultaneously, it was possible to downgrade parent frames from

  up to parent frames.
