User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:21.0) Gecko/20130119 Firefox/21.0
Build ID: 20130119030922

Steps to reproduce:

1. Create fresh profile. 
2. Install bugzillJS from here : https://addons.mozilla.org/en-us/firefox/addon/bugzillajs/
3. Set the settings as shown in the attached pic . (basically, enable "show inline changes to the bug")
4. Come to this page.
5. ctrl+click on  https://bugzilla.mozilla.org/show_bug.cgi?id=438871  
6. Observe some jank in scrolling.  

7. Switch to the tab opened in step  5.
8. Scroll up and down a few times (this is needed for bugzillajs to begin inlining)
9. Wait for a few seconds


Actual results:

HUGE janks. FF is  not hung at this point, but to external appearance, it look like FF is hung. Continues for about aminute, which is huge.
 The slow script dialog box also appears multiple times.


Expected results:

No jank, or possibly very less jank.
