Browser Bug Reproductions

I have an ever-growing collection of examples of different browser bugs (and jQuery bugs). I try my best to come up with these repros whenever I hit a bug, both so I can understand what's happening and so I can file proper bug reports. I will sometimes write up bugs that have been fixed in newer versions of the browser just so people understand them, especially with IE6 which still has a large market share.

Open Bugs

Old Bugs

These have been fixed in the latest version (or beta) of their respective browsers.
