Yes that is skipped.
Though from point of correctness it does not matter, since the dropped rectangle will be found in the next iteration, because 'foundRect' is still set.

From point of speed, I don't know if it matters, since at more complex regions you need multiple iterations anyway.
(Basically saying: I have no clue/assumptions on how the Rects within QRegion are sorted if so at all)
