I think this is a bug or perhaps just needs clarification:
If you use the view "front page" to display content on your homepage, this essentially creates a new path for < front >. As a result, setting a custom non-tokenized page title in the main meta tag menu Global: Front Page has no effect. In fact, any non-token title does not render.
To recreate: Go to views, enable view "front page" then change your path in site information to /frontpage. Then go to Global: Frontpage and set a custom title. This would reproduce the phenomenon.
So if you have set, for example, "Widgets for Sale" | [site-name] as your title, only the token [site-name] will show. (sidebar note: the metatag "description" tag still renders correctly).
So alternatively, if you were to create a "path" meta tag to < front > this will render correctly however I would ask if the Global: Front page item could point to < front > as well.
