InputPopup steals input devices and never gives them back

[A9G-Data-Droid]

If I open a custom input popup from the save menu I see the popup text and the pause menu text at the same time. I interact with both, which is an issue unto itself. Once both the popup and the pause menu are closed I can no longer look around with mouse or gamepad. I'm stuck in the mouse mode as if the input still belongs to ModHelper.Menus and not the game. The only way out is to quit the game. Full bork.

The calling code is doing this:
var popup = ModHelper.Menus.PopupManager.CreateInputPopup

Partially fixed by merge #404, but Pause menu and input popup still both seem to be interactable at the same time, so closing Pause menu before the popup will probably yield similar results
