pseudo-selector descendent selectors under html5 in IE fail

(needs html5 shiv or it collapses all elements)

$('header :visible').length 0

$('header').find(':visible').length 4

$('section :contains(give)').length 0

$('section').find(':contains(give)').length 1

reproduced in IE6 and IE8

This would be a problem with IE, not jQuery.

Paul is referring to this:

​http://ejohn.org/blog/html5-shiv/

I tried the obvious, defining the tags with createElement, and it didn't seem to help.

  document.createElement('header');
  document.createElement('hgroup');
  document.createElement('section');

I did notice in the html with IE8 debugger, the Sizzle sizcache and sizset attributes remain on the the elements. Not sure why that happens.

[paul.irish]

The shiv is in there now, but the above code is still reproducible.

I would be content with this as something that needs to be documented, but I'm curious if there is a fix available at the Sizzle level.

Try removing spaces before :visible "header:visible" and the same for contains.

Another testpage with spaces removed here: ​http://miketaylr.com/test/html5pseudo_spaces.html, with the same behavior.

​test case works for me using jQuery 1.4.4.
