Had to delete a test for key press with enter because of this bug in testing library: testing-library/user-event#554
It works to open the accordion with enter in the actual solution though.

Please add the test back and try this. If we dont have these types of tests, we cannot guarantee the behavior, and refactoring later on may lead to bugs. We shouldnt investigate other options before just removing tests.
