In the latest version the original test case worked, but I did some testing and setting -moz-user-select: none on the textarea made the problem re-appear.

<style type="text/css">
    div {
        -moz-user-select:none;
    }
    textarea {
        -moz-user-select:none;
    }
</style>
<div id="hiddendiv"><textarea></textarea></div>

Updated test case

Can someone please confirm this, and possibly assign it or something?

This is still an issue in 32.0.2.
Again, can this be confirmed and properly assigned?
