`default_scope` is an AR-reserved word and we're introducing a cop to
ban it, so this is a simple thing we can do to avoid a conflict. More
generally, we should never have used this name, since overriding AR
methods can have all sorts of pain.

This AR method does more harm than good, especially in large codebases.
https://github.com/rubocop-hq/rubocop-rails/issues/76 lists these
bits of evidence against it:

* https://rails-bestpractices.com/posts/2013/06/15/default_scope-is-evil/
* https://andycroll.com/ruby/dont-use-default-scope/
* https://stackoverflow.com/questions/25087336/why-is-using-the-rails-default-scope-often-recommend-against/

This prefers to use symbols where possible
for feature flag names

Fix design note scrolling

See merge request gitlab-org/gitlab!33939

Here we improve the test case for when we are
trying to ensure that a user without adminNote
permission is unable to move an existing note.

Previously, we were testing arbitrary details of the
component. Here, we simplify to test only
the outcome w.r.t the DOM (in this case,
the element's `style` tag).
