Revert "UI: Disable hotkeys when a user is expected to type text"

This reverts commit f832d14220.

Reverting this until we do more investigation. Currently, any text
that can be typed in a dialog requires the dialog to re-enable hotkeys
on destruction, which is frustrating. There has to be a better way.
