The word "tooltip" is shown in red as expected, but no tooltip appears when I hover over it. What am I missing?
Your code works for me. It's a little fussy though about placement of the text cursor. I had to position the tiny horizontal mark in the middle of the text cursor just *under* the word "tooltip" instead of directly over it.
