Thanks for checking. I’m not sure if this would be relevant to the repro but we were using it in a relatively complicated setup where i had a list of expandable areas inside a listview , each of which themselved held a listview in the body. I am unsure if that would contribute to the repro.
In our setup, I was not seeing the BodyBorder’s DesiredSizeScale being re-calculated via the call to SExpandableArea::GetSectionScale.
I _was_ seeing re-calculation of Visibility which was bound to SExpandableArea::OnGetContentVisibility , but not DesiredSizeScale…
If you dont see the issue in 5.4 either, i will try to see if i can make a more standalone repro.
