jQuery selectors search inside HTML comments, causing crashes and/or other errors

Reported by: MrPete Owned by: john
Priority: critical Milestone: 1.4
Component: selector Version: 1.3.2
Keywords: Cc:
Blocked by: Blocking:

Consider this scenario:


<div id="x">

<!--<small class="b"><a href="#" ></a></small>-->

<small class="b"><a href="#">Oct 3, 2009</a></small>




var str= $('small.b:first').text();

Will either crash FireFox (total lockup) or return an empty string depending on (something)

I'm using jQuery inside of GreaseMonkey, for whatever that is worth. But it appears this is a jQuery problem.

Sorry about the non-code formatting. My first jQuery ticket :)

Update: AFAIK, this is NOT a crasher bug. I've isolated the crashes to another issue.

The effect still stands, as demonstrated in my attachments: selectors "see" nonexistent elements inside of HTML comments.
