I experience the following annoying behavior: If the text in the minibuffer get's longer than the display width and lines are therefore continued on the next line, the minibuffer scrolling no longer works.
What I mean by that is that it "logically" works as when I press <down> or <up> the indicator correctly displays the number of the item I am supposed to choose when pressing <RET> yet I can't visually see what I would select.
First I thought it was a marginalia issue but that's not the case. With marginalia it only shows much more easily as marginalia adds text to minibuffer entries thus making lines longer. So this is a thing I can easily reproduce when making the whole Emacs window narrow enough to trigger continuation lines in the minibuffer.
Seems to be an issue with the highlight line logic and scrolling?
Emacs version 30.0.50
