What's Wrong?

When I run /resume to select a session, if I press the up and down arrow keys at the same time (which I did accidentally), the UI does an infinite loop between selecting 2 sessions (an index binding loop).

What Should Happen?

Pressing the up and down arrow keys at the same time should not create an infinite loop where I get stuck.
