[fix] Escape key exiting full screen while editing shapes (#1986)

This PR prevents the escape key from exiting full screen when a shape is
being edited or when shapes are selected. Basically, if the select tool
is going to use the escape key, then don't let it be used for its normal
purpose.

### Change Type

- [x] `patch` — Bug fix

### Test Plan

1. Open a firefox full screen tab.
2. Start editing a text shape.
3. Press escape. It should stop editing.
4. Press escape again. It should deselect the shape.
5. Press escape again. It should exit full screen mode.
