The problem is still there. The issue is that it actually changes the href in the link tag in html. Also, you have to actually use the Editor, and hit ignore to the suggesstions. Once it's finished, if you go and look at the "HTML" tab  in the editor, you will see that the link in href has been changed to lower case.
