Remarks

It sits over (or under) the menu it follows, in the same cell and without hit testing, and asks its subclass where the mark goes every time the layout settles. The slide itself is a transition on Border.indicator in Styles/Motion.axaml, with the rest of the motion.

The first time the mark appears it goes straight to its place: sliding in from the corner of the window would be motion that says nothing.
