don't jump back to selected slide on right click context menu

i.e. two many slides to fit in slide sorter panel, so scroll bar,
select slide one, scroll to the end and right click between slides
(or anywhere that isn't a slide) and without this fix the sorter
jumps back to make the selected slide 1 visible. The right click
menu will offer "new slide", choosing that will insert a slide
at the point that was originally clicked, not at the point it
was scrolled back to

losing focus trigger a (dubious looking) callback to jump to the
selected slide, so disable it while context menu is up
