Using find('*') on HTML5 tags includes closing tags in IE7 & 8

[Motty]

When using find('*') in IE7 & 8, almost all HTML5 closing tags are included (except for <ruby>)

This may be related to ​http://bugs.jquery.com/ticket/10047 but I opened a separate ticket just in case it isn't.

This appears to be happening in all jQuery versions.

This is because the tags are seen as invalid, notice what happens when Modernizr is included:

Any code that is expecting HTML5 tags to work should be including a shiv. This is really under the umbrella of the HTML5 ticket.
