why are you deleting this? enabling overlay scrollbars on aura/linux is a
recently added and useful flag.

Of course it's useful ... I was just proposing moving the flag's location. Given
your comments elsewhere I know propose we find another way that doesn't require
moving this flag out of content_switches.cc.
