Debug->Show Performance Data can freeze Brackets

[jeffkenton]

I have a case where I can freeze Brackets first try, almost every time:

I did a QuickEdit search that brought up an inline editor window. With that window still open, I clicked Debug->Show Performance Data. Performance data came up and Brackets was dead frozen. Sometimes freezes if I close the QuickEdit inline editor before Show Performance Data, but that's not as consistent. Sometimes freezes on any use of Show Performance Data, unrelated to QuickEdit. Also reproducible with Sprint 24.

Met one issue related to the issue above, so write it here:

Steps:

1. Launch Brackets and open the default sample folder.
2. Select the index.html file.
3. On the menu, click Debug > Show performance data.
4. Click the main.css file, or other files in this project.

Results:
After step3, the main.css file or other files can't be clicked and opened.
In @jeffkenton case,Brackets is completely freezed, but in my case, I can still do other operations,like: select a command from any menu.

@zhouweiwei1991 I think that is something different -- a very recent regression. See #5558
