Colon character in attributeHas (Browser compatibility)

[mark.andrus]

Given the markup

<div class="button" data-namespace:id="1"></div>

jQuery 1.7.1 will correctly parse the following in the latest Chrome for OS X, but not in the latest Safari or Firefox on OS X, nor in the latest Chrome or the latest IE in Windows 7

jQuery('.button[data-namespace:id="1"]')

Here is a jsFiddle demonstrating the issue:  http://jsfiddle.net/j84KA/

EDIT: Looks like two backslashes solves the problem, but this isn't mentioned in the docs

jQuery('.button[data-namespace\\:id="1"]')

Thanks for taking the time to try to help out the jQuery project, but this is not a valid bug. As is clearly stated in the selector documentation: "'If you wish to use any of the meta-characters ( such as !"#$%&'()*+,./:;<=>?@[\]`{|}~ ) as a literal part of a name, you must escape the character with two backslashes:"

As you can see, once the selector is escaped, it works fine.  http://jsfiddle.net/j84KA/1/
