You should be able to fix this problem by setting
hl-line-range-function to a suitable function (which should be quite
simple, AFAIU).

This is only true for the global-hl-line-mode; the local mode's
highlight is "sticky" by default, and shows even in non-selected
windows.
Moreover, you can customize the global mode so that its highlight is
sticky as well (not that I see why would you want to in this case).

Is this really important? Those are just implementation details, no?
