Select: fixes so component loses focus on selecting value or pressing outside of input. (#24008)

* changed the value container to a class component to get it to work with focus (maybe something with context?).

* added e2e tests to verify that the select focus is working as it should.

* fixed according to feedback.

* updated snapshot.
