Solution to my overlapping elements problem; I'm re-sending this to
gnome-shell-list so the (sort-of-)solution will make it to the
archives (I tried last Friday but the list was down).

That didn't work - the box & its contents were still underneath the bin:
layout = new St.BoxLayout({vertical: true});
layout.add(box);
layout.add(bin);
Mainloop.idle_add(function() {
// put into mainloop because box.height is styled in ems and if I
query straight away
// I get 'attempt to access theme node of widget before it was
added to stage'
box.anchor_y = -box.height/2;
});
However, what *did* work (similar to and inspired by this) was to add
the box to layout *after* the bin was added, and then setting its y
and anchor y relative to the `bin`:
layout.add(bin);
layout.add(box); // add this after so in an overlap this is on top
// now we have to move box vertically to the top of `layout`:
Mainloop.idle_add(function () {
box.y = 0;
box.anchor_y = box.height/2; // cause an overlap. Need the
mainloop for this .height request.
});
(And remove the `height: 1em;` from `box`'s style from my previous attempt).
There is still a slight visual delay though on initial display of
`layout` where it has the full height allocated at first and then a
little after shrinks (once the Mainloop.idle_add modifications take
effect). It'll do for now.
thanks!
