As a feature request, I suggest that the behaviour of the ComboView > Data window flyouts should be consistent.
This was partly (but not fully) adressed/reported in https://forum.freecadweb.org/viewtopic.php?t=17275 (bullet 1): the view collapses when changing the active part.
Unless a value has been changed/entered, which locks the state of the flyouts for some operations.
Anyone else struggling with this?
ps: i've filed the complete reproduction steps in the tracker: https://tracker.freecadweb.org/view.php?id=4358
