Undocked mixer dimensions and location ... still wonky in MuseScore Studio 4.3 (MacOS)

The MS4 Mixer resizing bug has been reported and stated as fixed in 4.3, but it still occurs on MacOS 13.5.2

Additionally you can see MuseScore's studio doesn't recall the location of the undocked Mixer, nor it's width, and essentially there is no undocked Mixer window minimum width.

Plus it's challenging to select the edge to change the width. And sometimes toggle the Mixer visible/invisible will crash MuseScore Studio, particularly when I've resized the undocked Mixer.
