This issue seems to happen on webkit nightly and chrome on a mac (does not happen on windows for either, haven't tried chrome linux).
This issue doesn't happen on Safari 5.0.3 or Firefox on the mac.
Downstream bug http://code.google.com/p/chromium/issues/detail?id=68487
The test url above shows the issue, click on the circles and a black border is seen.
See the attached image.
Also, in that test url, if you remove the css border and outline properties, clicking circles shows the normal focus border, which is correct, and no black border is seen.
Looks like this regression is due to http://trac.webkit.org/changeset/69237.
I can also reproduce this issue by tabbing through the areas, although behavior exists in shipping Safari 5.
yea it's pretty reproducible
Another site affected by this bug is http://www.conduit.com. Click the tabs labeled 'Create apps yourself', 'Promote & optimize', etc. to see the bug.

Adding a copy of the test case from the url since the old one was modified by it's original author to do a blur() onclick. So the issue wasn't being seen in the url.

Might want to get rid of the whitespace added here.
