I re-checked this assertions twice on my not-full-width panel, so let's
summarise :
- if expanding the separator (and with line checked) and iconbox is set to
"use available space", iconbox disappears AND line is drawn at the middle of
expanded separator (maybe i didn't see it last time) => conclusion, i can
only have one item expanded on the panel, and the last item expanded shrinks
the previous item which was expanded before.
- i confirm #2, and #3 seems the same for me.
Another idea would be to make the "expand" setting available (hidden or
greyed otherwise) in separator and iconbox only if parent panel is full
width and if no other item is already expanded, but this seems complicated
to me.

My previous posted patch doesn't solve this issue, but at least it makes
line and expand settings exclusive :)

I hope i managed to be clear :)
