The tabs of the meta-box and the meta-box itself have z-indexes of 1,
hence we need a z-index of 2 to ensure that the suggestions-page is
above them.

There have been some z-indexes that were removed and then reintroduced
through strange merges. This is an attempt to remove all z-indexes that
are unnecessary and to clearly state the purpose of the remaining
z-indexes in a comment to each index.

This removes the base z-indexes as they seem not to be needed (source
order defines initial heights) and interfered with the sidbar functionality.
Removing it was suggested in SPR-899 as well
