The repository list (all / favourites) and a repository's issues and pull
requests keep their header and tab row still while the list under them moves
the whole width. TabGlide in Motion.kt holds the movement.
A repository tab change reloads through Loading, which names no tab, so the
screen remembers the tab that was tapped and keeps the tab row up meanwhile.
