12450	Entities in attribute values are not encoded	Jakub Ś		"Paste below code in source mode:
{{{
<ul>
    <li data-title=""The UK&#39;s No 1""></li>
</ul>
<p>The UK&#39;s No 1</p>
}}}
Switch to wysiwyg mode and back to source:
{{{
<ul>
 <li data-title=""The UK's No 1"">&nbsp;</li>
</ul>
<p>The UK&#39;s No 1</p>
}}}
Result: attribute value is has ' instead of &#39;. It seems that entities in attribute values are not encoded.
