OK, I see the behavior described in the OP now.

But I don't understand why is this behavior interpreted as a bug.  If
I type <RIGHT> arrow or C-f enough times, I eventually do see the red
line on the right edge of the rectangle.  So this is just the normal
horizontal scrolling of images plus automatic clipping of images in
action.

I see no bug here.  What am I missing?
