[Message part 3 (text/plain, inline)]

If you make a bookmark to a webkit xwidget (i.e. to a URL displayed by
the xwidget) and then use `bookmark-jump-other-window' or
`bookmark-jump-other-frame' to jump to the bookmarked URL, the xwidget
is displayed in both the original window and the other window or other
frame.  Also, if you try to jump to the bookmark in an Emacs session
before loading xwidget.el, it fails with an unknown symbol error.  The
patch below fixes these issues for me.

2021-12-28  Stephen Berman  <stephen.berman <at> gmx.net>

	Fix handling of webkit xwidget bookmarks

	Make jumping to a bookmarked webkit xwidget in another window or
	another frame show the xwidget only in that window or frame.  Also
	make jumping to the bookmarked xwidget possible before explicitly
	loading xwidget.el (bug#xxxx).

	* lisp/xwidget.el (xwidget-webkit-bookmark-jump-handler): New
	autoloaded function.
	(xwidget-webkit-bookmark-make-record): Use it.

Yes, and I also have write access to the Savannah repo, so I went ahead
and pushed the change to master as commit 95ee6e8b90 and am closing the
bug.  Thanks for your feedback and advice.
