If your network access is not in hight speed, this may be hard to reproduce. I
recommend to save the query page as local file. If it is still hard to
reproduce, scroll the page a little.

The symptom here has been fixed.  Does this patch actually implement the code
required to fix bug 121264?

Comment 12

Yes, I think it does.
