Steps to reproduce:

1. Open TroubleShooter
2. Start spamming large amounts of text in the search bar
3. Once you reach a very high amount, you should eventually hit the upper limit
4. TroubleShooter freezes

Expected result: Whatever limit for the characters you reach, it shouldn't freeze the troubleshooter window
Actual result: Upon spamming too much text, troubleshooter window freezes and needs to be re-opened
