Simple Canvas drawing rendering incorrectly
User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:12.0a2) Gecko/20120219 Firefox/12.0a2 Build ID: 20120219042015 Steps to reproduce: Open this URL http://jsfiddle.net/codepo8/ccvxy/ Actual results: It drew a circular pattern in a new canvas element that did not look like a spider's web Expected results: Drawn a spider's web.
The page renders correctly in the Firefox 10 and Webkit.
Adil, would you be willing to find the regression range by any chance?
Looks like a regression in this range: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=34572943a3e4&tochange=f4049f65efc6 Almost certainly a regression from Azure canvas on OSX.
Do you see the same problem on windows?
On Windows, I see correct rendering in both Firefox 10 and today's nightly.
From a quick test this issue started to happen from FF 12 on the Mac. I did not see the issue in FF 11.
This was a copy&paste typo

Tracking for Firefox 12 and up since this is a recent regression and may cause web compatibility issues. The fix seems low risk, and we'd therefore like to get this uplifted to Aurora 12 if you agree.
