GitLab adopted @gitlab/ui^3.0.0 during the lifetime of this branch. The
breaking change introduced the GlSearchBoxByType and GlSearchBoxByClick
components, and removed the GlSearchBox.

What this (and the previous) approach aims to achieve is *not* to show
a scrollbar in the severity filter dropdown. It's a fixed list of
severities, and inside a `dropdown-content`, the dropdown items are only
*just* tall enough to be taller than the max-height of
`dropdown-content`, making it render with a scrollbar, looking terrible.

The report type filter dropdown is also a fixed list of only four items,
so also doesn't need an internal scrollbar.

The projects filter dropdown, however, is not a fixed list, and requires
the internal scrollbar provided by `dropdown-content`.

It takes options objects (id/name key/value pairs), not `Map`s.

This approach gives us two things:

1. Exact strings are verified, rather than more loosely checking for
   a substring
2. Should the string change in future, these tests no longer have to
   change. The purpose of them is to verify that some constant is
   returned, but they don't care what that constant actually contains.

Previously the `|| null` was ensuring that the return type of the helper
function was `HTMLElement | null`, rather than `HTMLElement | null
| undefined`, which allowed the tests to check against just `null`.
Instead of documenting that oddness, this just changes the tests to
expect an HTMLElement (or not), removing the need to avoid `undefined`.
