Poster attribute not being removed from video tag

[pgmahoney]

I have found that the poster attribute is not being successfully removed from the video tag, after the poster img tag has been created.

tag.removeAttribute("poster");

results in poster="" in Firefox and poster="null" in IE. This causes the browser to try and fetch the current page as the poster image in Firefox, and a 404 in IE.

To fix this, I have had to add:

tag["poster"] = null;

Video.js 4.0 is out now, so this issue may be fixed or out of date. If you think it's still an issue, please check using 4.0 and reopen.
