When the mytuleap_contact_support plugin is installed and activated, an additional asset is loaded on almost every page to open a modal to contact the myTuleap support when someone clicks on a link in the floating help button.

In tracker artifact pages, there is a special query parameter that loads the page in "printer version" and removes a bunch of things like the sidebar and the help button. Our javascript asset is designed to throw an error when it cannot find this button, but it should silently ignore it and do nothing instead. If the button is not present, the modal cannot be shown anyway.
