Changeset #115803 tried to reduce issues regarding the statusbar
chevrons wrapping in an ugly fashion when the number of buttons increase
in the header.
Unfortunately, this has side-effect in other cases which actually
degrade the experience.
This commit removes most of that changeset, with the exception of
keeping the -flex-wrap on header buttons - it's better to break the list
of buttons over 2 lines than breaking the buttons themselves into 2
lines.
