After updated from DNN 7.02 to 7.04 some of webpage links are seems not working (I have added the links using html module). And those links have some common attribute that is link description contain "-" character once I upgrade the environment "href" tag also need an "-" character.

EX: before update

<a href="Testpage.aspx" <img src="/portals/0/Images/Lab-img.png" alt="Test-page" /><h4>Test-page</h4> <p>Test-page</p> </a>

After Upgrade

<a href="Test-page.aspx" <img src="/portals/0/Images/Lab-img.png" alt="Test-page" /><h4>Test-page</h4> <p>Test-page</p> </a>

what would be the reason
