 Pixel scrolling and scroll-margin don't work together smoothly

[Message part 1 (text/plain, inline)]

Setting '(pixel-scroll-precision-mode 1)' with '(setq scroll-margin 5)' (or any other non-zero value) creates a conflict where the pointer just
can't move further while using mouse scrolling. Without '(pixel-scroll-precision-mode 1)' mouse scrolling with the scroll-margin works fine.

Adding Po Lu.

Does it make sense to use scroll-margin with pixel-precision
scrolling?

In theory it does, and we are aware of this issue.  The challenge is
that any attempt to account for a scroll margin screws with scrolling
tall images, and we currently consider the latter more important, and as
such configurations with both a scroll-margin and p-s-p-mode enabled are
not supported.
