Steps to reproduce the problem:
1. Open Developer Tools
2. ctrl-shift-F to search for a class or method
3. Observe

What is the expected behavior?
The line I'm looking for is found relatively quickly.

What went wrong?
Chrome becomes amazingly slow (to the point where its somewhat unusable) and the tab devtools is attached to completely freezes up. 

Note: this doesn't happen every time, but it does happen frequently enough to become bothersome.

Did this work before? N/A
