CCAe window resizes/resets when changing RBG/HSL/HSV slider mode

[patrickhlauke]

After changing the View > Zoom to something other than the default, the window/its contents do weird resizing stuff and reset the zoom level when switching between RGB/HSL/HSV slider mode

Desktop (please complete the following information):

• OS: Windows 10 64bit, macOS Catalina 10.15.7
• Version CCAe 3.1.2

To Reproduce
Open CCAe, change View > Zoom, open the sliders panel for foreground colour, change the RGB/HSL/HSV buttons

Expected behavior
Zoom level to remain the same

Video recording (on macOS - Windows behaves the same though) https://www.youtube.com/watch?v=avAKBSiHlNw

Yes, I found this problem few weeks ago.
This issue is a mystery:
For some reason the zoom factor is modified if you click on the tab buttons...
I couldn't figure out any relation between the tab button and the zoom factor.
