// property to store SharedSizeGroup state, except property inheritance is done
// down the logical tree. In this case, the control which is setting
// Grid.IsSharedSizeScope="True" is not in the logical tree. Instead of fixing
// the way Grid stores shared size state, the developers of WPF just created a
// binding of the internal state of the visual parent to the menu item. We don't
// have much choice but to do the same for now unless we want to refactor Grid,
// which I honestly am not brave enough to do right now. Here's the same hack in
// the WPF codebase:
