Given I am Siteadmin,
When I edit an existing custom service in any project and I click on the "Available (also available for new projects)" switch, then it looks like it does nothing.
Actually, it does something. Since the "Add a new service modal" is present on the page and the label and checkbox input had the same HTML id, when I click on the button in the "Edit modal" it actually triggers the switch in the "Add modal".
