In that case it is not clear how to use this view. I would have expected a Popover view to take a template (which is what would be used for the popover text). From this code I'm guessing `params.owner` contains the HTML to render but only because it's the only variable that isn't used elsewhere in this file.

Please document how this file should be used.

Can you also explain why the popover needs to be configured in 2 places: one for the owner element which comes from some other template and then in here? That seems confusing to me.
