title: iPad popover not resizing properly after search keyboard is dismissed
body: <p>I have a popover that contains a tableview (which is inside a navigation controller) with custom cells and a search bar in the header. Once I enter the search bar the popover shrinks appropriately to make room for the keyboard. Good so far. Once I dismiss the keyboard either by pressing the search button or the dismiss keyboard button, the popover appears to resize a little but does not does return to the full length as I would expect. I've tried all the suggestions to update the popoversize and contentsizeinpopover. They seem to have no effect. </p>
  
  <p>Any thoughts or workarounds?</p>
  
  <p>Thanks,</p>
