Steps to reproduce:
1) Open users attached project.
2) open profiling and enable deep profiling
3) After one second, a script will execute a very deep call and create a peak in the profiler.
4) Select the peak.
5) Now try to drag the profiler window or click items. It should be much slower than normal.

Actual: it takes around .5s for every click in the profiler regardless of whether you are expanding or just selecting
Expected: it shouldn't 'lag' navigating editor unless you are expanding or changing something in the editor
