If HTML tag attribute value contains ' in it is getting converted to ' .

Hi,

We have a requirement , in our editors if we give ' as a value to one of the HTML tag attributes it is getting converted to ' . Below is the example

Given  <li data-title="The UK&#39;s No 1"></li> , Once we close and open it is getting converted to <li data-title="The UK's No 1"></li>.

How to stop the conversion from " &#39; " to " ' ".

Note : If we give &#39; as a tag value ex: <p> UK&#39;s No 1 </p> , It stays as it is as <p> UK&#39;s No 1 </p>. It is only a problem if this escape character exist as a value of an attribute.

Can anyone faced this issue before ? If so can you guys help me ?
