It makes sense to improve UX which this test shows.

1. ShowIfRedirected()
2. Show (user opens window manually i.e. overriding automatic behaviour for
opening)
3. Close (i.e. user closes window manually i.e. doesn't want it to popup)
4. Redirect happens - I thinkg that CP window should not open automatically.
Let's consider (2) and/or (3) as user "manual override over automatic open
behavior".

If user opens window manually and then proper redirect happens (i.e. to original
URL) then it is OK to close window automatically (this case is already tested
here).

Done.
