BUG creating a link overlapping end tag

Consider the following code:
<strong>blah A blah </strong>blah B blah

If I select text from A to B and create a link, the following code is generated:

<strong>blah <a href="http://link">A blah </a></strong><a href="javascript:void(0);/*1166175937000*/">blah B </a>blah

Note that the link is cut in two, and the href of the second link is a faulty javascript:void(0)
