            Bug ID: 225178
           Summary: Canceling a print request results in empty preview on
                    subsequent requests - can hang Safari
           Product: WebKit
           Version: Safari 14
          Hardware: Mac (Intel)
                OS: macOS 10.14
            Status: NEW
          Severity: Major
          Priority: P2
         Component: Printing
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: l.mazz at verizon.net

1.  Open a wine list in my web app
2.  Try to print it…

      A.  The first time:  I get a print panel with the result in it.
            If I hit “preview as PDF”, I see it rendered just fine.
            I can view and close the preview window.
            THIS IS REPEATABLE.

      BUT

      B.  If i hit “Cancel” in the print form, the next time I try to print the
            wine list, I get a blank (and apparently intinitely long) preview panel.
            If I hit “Cancel”, I return, and get the same empty but infinite preview if I try to print again.

            IF I HIT “preview as PDF” and then try to cancel, IT HANGS SAFARI:

HERE"S AN EXAMPLE FROM ANOTHER USER:

Click "See the demo"
Click "Print Kittens" = first time OK, second time: nada.  Same symptoms as above
