hunch

https://github.com/jcubic/jquery.splitter/blob/944fe5a0273f3e2fa44e7d9462824ae4daa4ed41/js/jquery.splitter.js#L438C25-L438C39

`leftUpperLimit` is defined here, but not used. There is an extensive dimensions check below that - which I haven't started to wrap my head around.
But my gut tells me that one of those ifs the formula is using `rightBottomLimit` instead.

excuse for the bothering if the hunch was invalid.
otherwise: thank you for the splitter!

Start in js/jquery.splitter.js around line 438 and inspect how leftUpperLimit is defined and how the dimensions checks below use the related limits. Determine whether the suspected rightBottomLimit reference is incorrect, then verify that the corrected limit behavior remains consistent across the splitter's dimension calculations.
