This reverts commit 7cecc8e524.
It is impossible to use the selection object of the menu while it is
collapsed (collapsed menus deselect everything for a start), so even
though the original patch was correct, the followup issues are too big
to solve this quickly to a release.

The fix for child properties made the a11y dump for the assistant
case change. After close inspection, the new output is what the
code intends to produce, so update the expected result.
This value is highly sensitive to changes in the theme; we
don't want to have to tweak hardcoded integers in this test case
every time we rev gnome-themes-standard.
Future iterations could do more heuristic matching, but this
is enough for now.
