the Restore and Exit menu uses mouse

[g0dd4rd]

1. press escape key
2. navigate to either exit or restore menu options and press enter

result: suddenly no keyboard available, only mouse with no invisible pointer which makes it hard to navigate

expected result: preserve the keyboard driven navigation

This is a good point. I think there are two issues:

• [x] cursor should only be invisible within the game scene (not globally). Fixed in 11.18
• [ ] keyboard navigation needs to be refined (which could be a result of early event filtering to avoid navigating between scenes and subscenes, e.g. when dialogs are open)
