QSplitter: moving a handle that is in front of a collapsed widget will incorrectly un-collapse the widget

In a QSplitter with multiple widgets and handles where one of the middle widgets is collapsed, that collapsed widget will effectively have two handles surrounding in.

Moving the handle behind/under the widget should un-collapse the widget, and it does.

However, if the handle that is in front/above the collapsed widget is grabbed and moved, the hidden widget will suddenly appear, although it should not.
