* If a context_page was shown, the focus for the panes didn't work.
By clicking all panes you could get input in all of them as long as
the context_page prevented focus updated.
* Find was drawn in all panes, with typed text being entered in all of
them. Changed this to only show find in the focused pane.
* Also, when I was going find related stuff, I populate the find entry
with selected text, and clear the find search value on close.
