Testing the visibility / presence of things around
the dialog appears to be hard and the DOM for the dialog
remains unchanged when shown / hidden as far as I can see.
These tests test that the dialog is only shown once per
user.
And that the sequence of the dialog works in regards to the correct
buttons being present at the correct times.

This adds 1 simple browser test to make sure that the placeholder
for the revision slider loads when the beta feature is enabled and
does not load when it is disabled
More tests will follow.
