http://mxr.mozilla.org/mozilla-central/source/gfx/layers/FrameMetrics.h?rev=1002b028b6c4#146 has a thing that references bug 775452 which is now fixed. The comment should be removed/updated.

We have three references to this bug - http://mxr.mozilla.org/mozilla-central/search?string=bug%2B775452 We also have a few mentions of BrowserElementScrolling in apz code, which form my understanding is no longer in use? http://mxr.mozilla.org/mozilla-central/search?string=BrowserElementScrolling

Which is still currently in use (bug 970125 to remove it).
