Window is not properly resizeable after set_title_bar in OSX
Steps to reproduce
- start gtk3-demo and there the HeaderBar demonstrator
- try to resize/move to the right half of the screen with one of the OSX resize tools, e.g. spectacle or recangles
Current behavior
the window moves a little bit, but keeps its size
Expected outcome
the window moves and is resized according to the wishes of the external program. if you change the windowsize manually with the mouse at the window borders it works.
Version information
gtk3-demo 3.24.12
