Mouse and Keyboard Unusable while Incoming Damage tab open in Spectator Mode

[jasonw4331]

While spectating a match hold the tab key and click on a player at the top of the screen. Then, hold the tab key and click on the incoming damage dropdown. Your mouse will disappear and your keyboard will be come unresponsive. Pressing 'J' to reshow the mouse yields no response and the escape key does not open the menu to leave spectator mode. After what appears to be a random amount of time, the keyboard will register one input before being unusable again.

In the attached video I press tab and escape, jiggle my mouse repeatedly, and switch characters attempting to bring back the mouse.
