Some behat steps are clicking on "Option" elements instead of using field steps.

In recent versions of Marionette (part of Firefox automation stack) this causes an error.

A little more archaeology.

In Firefox 103, a change to the Marionette driver to refactor the Actions code led to more error checking of this condition.
This was introduced via https://bugzilla.mozilla.org/show_bug.cgi?id=1773264 in this commit.

The change is correct, but was not communicated well.

I've commented on the relevant issue: https://bugzilla.mozilla.org/show_bug.cgi?id=1773264#c8
