Plugin components flicker/jump when tweaking the graphic UI in Inspector. This seems to be specific for plugins that have a graphic interface that the user can tweak.

Please see attached video for details (although not all the flickering is captured by the video frames)

To reproduce:
- Open attached project and launch "test" scene
- Open the "test" audio mixer and dock the window
- Hit Play and enable "Edit in Play Mode"
- Select the "BD" audio group
- Go to Inspector and tweak the vertical white lines on the Demo Equalizer
- Observe the flickering/jumping components in Inspector
