I can reproduce it here with (setopt frame-resize-pixelwise t) and
dragging the bottom border of the frame up so the eshell window doesn't
have an integral number of lines.

'pixel-scroll-precision-mode' sets 'make-cursor-line-fully-visible' to
nil so this is probably the intended bahavior.  When I do

(setq-default make-cursor-line-fully-visible nil)

I can't see it any more.
