Resizing window scrolls away from text location

1. Open Assitant.
2. In Index, search for QMessageBox::Question and open the page found.
   You'll see related documentation.
3. Resize the window. For most obvious results make it much narrower.
   While the documentation page is being rewrapped, the interesting location will scroll out of view.

Assistant should still show the same location after resizing the window.
