Thanks for walking me through this!

❓ question: ‏any reason to have a scroll triggered on click rather than scrolling directly?

[N-Boutaib]

Not really, I just wanted to have a way to trigger the scroll once everything is setup (calling scrollTo on the element from the test isn't working because the returned wdio.Element doesn't allow this)

[bcaudan]

Making the test itself trigger a scroll would be easier to follow but if it is not possible, adding a comment that clarify the intent could help
