Test Dropdown Focus Management && Bugfixes

[marcus-herrmann]

@ovlb From the start on I tried to test focus management, but it always failed.

Leaving the approach below as a note-to-oneself / a how-to for improving existing and writing new tests.

@marcus-herrmann Here are the bug fixes: 2e2f4ef and 1c06de6

[ovlb]

I always don’t know if I fix bugs because they are bugs or if they are only «bugs» in Storybook. But I think the focus management thing is a real bug.

[ovlb]

@marcus-herrmann Can I merge this?

[marcus-herrmann]

@ovlb I can't really speak for everything but commit fd7bab7, but in this case, yes.
