Youtube Video Quality Button Tests

I think it is useful to have blank line after first in such docstrings. I think this speeds up readability.
What you think?

"""
        Scenario: Quality button works correctly.

        Given the course has a Video component in "Youtube" mode
        And I click video button "play"
        And I see video button "quality" is inactive
        And I click video button "quality"
        Then I see video button "quality" is active
