Please add a test to BrowsingDataRemoverTest.

Done.

The guarantee that we want to give when the user deletes history is that no URLs
remain stored anywhere (except search engines and content settings which have
their own UI, so they're auditable separately).

So please add a REMOVE_HISTORY condition as well - for example by moving this
three lines below.

Unless this listens to local history item deletions, as SITE_ENGAGEMENT does
(IIRC). In that case it's OK not to specify REMOVE_HISTORY explicitly, but add a
comment instead.

[dominickn, 2016/08/09 08:31:24]

Done.
