title: Why would a link in a UIWebView leave a gray box behind?
body: <p>I have a UIWebview that I am loading with custom HTML using loadHtmlString.   My HTML has a   link that I intercept when tapped so that I can take control and reload the UIWebview with a different HTML string.  The code works, but the area where the link text was located is replaced with a gray rectangle that is visible when the new string is loaded.   </p>
  
  <p>What could be going on here?  How can I get rid of this behavior?</p>
