html and css showing buggy area in red

I have attached a situation where there is a gap injected between lines arbitrarily.  This seems to be related to the combination of exclusions/regions/widow/orphans.  Where when removing exclusions from one of the earlier elements or removing or changing the values of widows/orphans seems to effect the outcome.  The split can be often found in the example region in red.  This seems to only occur under specific circumstances and can be tricky to recreate, however it does cause a very obvious issue where there appears to be a random break within content.
