I was not sure how to categorize this, so apologies. When viewing any embedded video, and opening another tab, the video will leak through. This was reproduced on Mac OS 10.5.1, consistently, without fail. Heres the steps to reproduce. 1. Go to an video site (such as youtube link) 2. As it is playing. open a new tab. 3. Switch back and forth and on the tab that is not plaing the video, the video from the tab behind it will leak onto the current tab. This is reproduced with latest nightly. This is not produced when using Safari 3.0.4 without nightly build, which makes me think it is a nightly build issue.
