`PressableButtonHoloLens2Toggle_32x96_Dwell` does not change off-color

[turbotimon]

Describe the bug

The Toggle-Button does not change color as set when toggled. (The function ButtonExecute in ToggleDwellPressableButton.cs is never executed.)

To reproduce

Steps to reproduce the behavior:

1. Add a PressableButtonHoloLens2Toggle_32x96_Dwell to your scene
2. Change dwellOffColor to e.g. red
3. Go to play mode and toggle the button
4. See that color doesn't get changed (well it does, but not to the color set, e.g. red)

Expected behavior

Color gets changed

Screenshots

Your setup (please complete the following information)

• Unity Version 2020.3.37f1
• MRTK Version 2.8.3

Target platform (please complete the following information)

• HoloLens 2

Additional context

These code in ToggleDwellPressableButton.cs is never executed:

        /// <inheritdoc/>
        public override void ButtonExecute()
        {
            Debug.Log($"ButtonExecute {isDwellEnabled}"); // DEBUG test, to see it is never executed
            isDwellEnabled = !isDwellEnabled;
            dwellStatus.text = isDwellEnabled ? "On" : "Off";

            // swap the button background and dwell visuals overlay color
            buttonBackground.material.color = isDwellEnabled ? this.dwellOnColor : this.dwellOffColor;
            dwellVisualImage.material.color = isDwellEnabled ? this.dwellOffColor : this.dwellOnColor;
        }

in addition: the field bool isDwellEnabled is logically rather a isToggled or not?
