`minibuffer-message' and `set-minibuffer-message' place the overlay containing the message slightly differently, resulting in a different behaviour when there are other overlays present at the end of the minibuffer. The overlay created by `minibuffer-message' always gets added to the end of the minibuffer. The overlay created by `set-minibuffer-message' also gets added to the end of the minibuffer, but its properties make it so that it is shown before other overlays at the position. This is particularly important when the user uses packages that add overlays to the minibuffer, such as vertical completion packages like selectrum, vertico, and others. The way `set-minibuffer-message' configures the overlays makes it so that the overlay is displayed before the other overlays, which I believe is more compatible with external packages (see attached image for a visual example). Would it make sense to change this behaviour (i.e. overlay configuration) so that it is consistent in both functions?
