This allows us to fix a bug where when our current Private Browsing shortcuts are pinned to the Start Menu, they use the regular Firefox Visual Elements (which is the non-Private Browsing logo). I tried to make this as minimal and braindead as possible. Differential Revision: https://phabricator.services.mozilla.com/D151538
