The testcase lays out four different scenarios for the links toolbar: - Single link of unrecognized rel, no title This definitely needs to be fixed. This should be a top-level choice, like Authors and Copyright, and not be in a submenu. - Single link of unrecognized rel, with title Debatable. Title could imply being part of a group, so it should be in a submenu. Title could also just be a more readable version of the rel, such as how we display Table of Contents for contents or toc, so it should be a top level item. - Multiple links of unrecognized rel, no titles Difficult to handle well. Should definitely be in a submenu, but all the choices have the same name and thus aren't very helpful. I think we should use the rel for the menu and the href for the choices. Not great, but better. - Multiple links of unrecognized rel, with titles This is fine. Submenu is rel, choices are titles.

Haven't worked on Mozilla for several months and this is unlikely to change soon.
