There were actually two separate logical errors in this method:
The first part is that "origSizes.isSome()" is simply a bogus
requirement for applying min/max-sizes here. I'm still keeping
the optimization of not needlessly copying the mSizes array
(as originally intended) since it's a quite common case.
The second bug is that min/max-sizes were only applied under
the "if (fr != 0.0f)" block. This is bogus since the calculated
'fr' value depends on 'aAvailableSize' which might change by
applying min/max-sizes and thus 'fr' could become non-zero in
the second round.
To fix, this patch just moves "applyMinMax" block out one level.
