changelog Dangerfile that is been triggered on security MRs. This commit

changelogs for security merge requests.

Resolve "MR right sidebar is off when scrollbars are visible"

Closes #196226

See merge request gitlab-org/gitlab!27314

Some users reported being logged out quite frequently, and we suspect
a change in Chrome caused this.

Chrome v80, rolled out in March 2020, treats any cookies without the
SameSite directive set as though they are SameSite=Lax
(https://www.chromestatus.com/feature/5088147346030592). This is a
breaking change from the previous default behavior, which was to treat
those cookies as SameSite=None.

To fix this, we add a middleware that tags all cookies with the Secure
and SameSite=None headers. This middleware is needed until we upgrade to
Rack v2.1.0+
(https://github.com/rack/rack/commit/c859bbf7b53cb59df1837612a8c330dfb4147392)
and a version of Rails that has native support
(https://github.com/rails/rails/commit/7ccaa125ba396d418aad1b217b63653d06044680).

Re-structure Analytics documentation index

See merge request gitlab-org/gitlab!28153

Previously the Analytics documentation index was built around the
Analytics Workspace concept. It did not sufficiently explain features
located outside the Workspace. Plus, we are moving away from the
Workspace concept anyway. This re-structures the Analytics
documentation index into 3 sections: instance (Workspace), group and
project levels. The Analytics features available are explained.
