No, I mean the slider jumps back to the left edge, whereas it started
at the right edge (which is correct for R2L lines).

Well, it was you who mentioned suspend_auto_hscroll as the possible
cause for the slider behavior when I click on it.  If
suspend_auto_hscroll is not related to that problem, then I ask again:
where's the code which causes the slider to jump to the left when I
click on it?

I experimented with only one window.  I intended to try with several
windows showing the same buffer after that.  However, testing with a
single window (which was obviously selected) failed to produce the
desired behavior, so I never proceeded to more than one window.

What I did was temporarily move point to the window-point, then call
current-bidi-paragraph-direction.  Maybe there's something wrong with
