nit: I don't think this comment (and the other ones) add a lot of value. Setting
"activation type" to "contents clicked", which you get by reading the code, is
obvious enough. Up to you.

I rather leave it, I totally hate repeating it on every test though. I do think
it's important to mention
that this is a test artefact and that in real life the  OS does it for us.
