Title: RibbonMenuButton and RibbonToggleButton fixes

Fixed - Toggle button should have the same look when pressed both checked and unchecked

Fixed - MenuButton should not stay dark after the popup opens
It should go to the highlight color

**Note**: However it does not go dark when you press it. It goes straight to IsChecked mode
