Warframe frequently loses input events

[oolgorboid]

 

Mousing between menus and pressing A on the controller to select a menu option doesn't work. Warframe loses the first input event while the UI switches from KBM mode to controller mode.

This happens frequently on Steam where a single input device can emulate keyboard, mouse, and controller input simultaneously.

This issue was introduced with the UI rework and still remains a problem.

Also, the arsenal, foundry, and other inventory menus become confused when the input mode changes in the middle of things.
