I’ve found an issue with using a smart-grid inside a smart splitter and smart-grid % height setting.
I have a smart splitter that uses three sub panels horizontally aligned: left, middle, right
The smart-grid is set into the middle panel with a 100% height
If I ‘hide’ the left panel by clicking on the ‘<‘ splitter icon, then the smart grid height changes to beyond 100%
If I change the smart-grid height to 98% and then repeat the ‘<‘ click then the smart grid height is correctly not changed.
