<span class="quote">&gt; css3-ui states that the resize property applies to “elements with ‘overflow’
&gt; other than visible”, which includes pseudo-elements.</span >

The css3-ui spec now also says &quot;Implementations should not apply the resize property to generated content.&quot;  That includes the pseudo-element in the dabblet testcase here.
Spec link: <a href="http://dev.w3.org/csswg/css-ui/#resize">http://dev.w3.org/csswg/css-ui/#resize</a>

So, I think the (current) expected behavior here is that WebKit shouldn't be showing a resizer on that pseudo-element. (The resize property &quot;should not apply&quot;, i.e. it shouldn't affect rendering at all.)

Incidentally, Firefox/Gecko recently changed to have that behavior (not showing a resizer) in <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=1043537">https://bugzilla.mozilla.org/show_bug.cgi?id=1043537</a></pre>
