Doesn't work in the editor with Configurable Enter Play Mode

[Romaleks360]

The picker stops working properly when fast enter play mode is enabled. The most obvious effect is that the hue slider on the left is white (ColorSliderImage's Awake is broken). There are also occasional errors in the console.

ExecuteInEditMode/ExecuteAlways scripts are not destroyed/awaken - no OnDestroy/Awake calls for those.
Watch out for Awake/OnEnable methods which check EditorApplication.isPlaying property - Awake is not called and OnEnable is called only when EditorApplication.isPlaying is already true on Play Mode change.
