Steps to Reproduce the Bug

1. Determine the hotkey to test (I picked IC2C's toggle key; set as "F")
2. Meet conditions for the hotkey to trigger, if any (in my case wear the jetpack and see that "F" turns it off and on successfully)
3. Open JEI, search something with the letter "F" in it.
   Expected Behavior
   Following the steps to reproduce the bag 1-3 the fourth step must be:
4. Go on searching and watch that all hotkeys are blocked from executing while the search box is focused (or at least when the inventory is opened).

Actual Behavior
Watch the jetpack triggers every time you press "F". (Same applied to AE2 terminal; it is set to synchro with JEI).
It does apply to all
