FoldoutGroup does not remember its state while selecting and unselecting similar objects in Hierarchy

[jpetays]

I have four FoldoutGroups and their collapsed and expanded states behaves erratically when I switch selection from one object to an other or use multiselection and single selection.

AFAIK UNITY Inspector remembers collapsed and expanded states (for applicable objects, like arrays or [Serializable] objects) perfectly.

For my case it seems that two lowest FoldoutGroups ("Highlight Sprites" and "Pickup Image") work perfectly but the other two do not. They are losing their collapsed/expanded state when selection changes between different objects in Hierarchy.

For my project this is absolute no-go while evaluating to switch to Alchemy as you might loose some important UNITY Editor/Inspector quality of life features!

    private const string I1 = "Static Effect is when there is no Animator or AudioSource";
    private const string I2 = "For looping effects there can be some (random) delay between animations.\r\n" +
                              "This is controlled by 'some other' settings how this works.";
    private const string I3 = "Plays along main Effect Animator";
