This reproduces for me on macOS only if the window is on a lo-dpi display. On the hi-dpi (retina) display, the mouse pointer moves directly from the up to down arrows (or vice versa), but on a lo-dpi screen there's one pixel at the boundary where neither arrow button is highlighted, and the cursor reverts to an I-beam.

Severity: -- → S4

The arrow icon sizes can differ as well at certain UI scaling levels, see bug 1670912.
