Subject: 30.0.50; hl-line overlay priority has no affect
Date: Thu, 30 May 2024 23:27:02 +0100

Hi there,

Looks like there's no way to give hl-line a higher priority than other
text overlays. This impacts things like eglot-inlay-hints-mode or
overlay-error-string among other modes and has the affect of making
hints or annotations from these modes look out of place. I can reproduce
this with something as minimal as:

$ emacs -Q
$ M-:
(progn
  (setq hl-line-overlay-priority 10)
  (hl-line-mode)
  (erase-buffer)
  (insert ";; This buffer is for text that is not saved, and for Lisp evaluation.
;; To create a file, visit it with ‘SPC f f’ and enter text in its buffer.")
  (let ((ov (make-overlay (+ (point-min) 2) (+ (point-min) 3))))
    (overlay-put ov 'before-string "foo")
    (overlay-put ov 'priority 5)))

If you move the point to the first line you can see the overlay and its
face background completely disregards hl-lines background despite having
a lower priority.
