title: Multiline UITextView in UIScrollView selection not working
body: <p>I have a multiline UITextView that sits in a UIScrollView. It's configured to be editable and selectable, so long pressing brings up the standard Select/Select All, etc menu. If I tap Select All I can only resize the selection on the first line. Once the selection changes to not include the first line the selection handles no longer respond to touch input. </p>
  
  <p>If I select a single word on the first line, the left selection handle functions normally, but the right handle doesn't receive touch input.</p>
  
  <p>Any ideas what might be causing this? This is very strange and I can't really figure out what's going on. I'm not overriding any gestures (that I can tell, anyway).</p>
