It will never cease to amaze to me that Apple (under Jef Raskin who also wrote about this in The Humane Interface) observed and fixed problems with interactions like this in SYSTEM 6 in like 1993 or something - only for the same problem to have to be re-descovered and re-fixed decades later.
There was another similar loss and discovery about non-linear geometry of submenus. Most websites build it naively so that once a submenu has opened, you must guide your mouse very carefully toward it or it will close again. There is a better approach that allows for less precise and faster reach, but it requires some geometry when tracking the mouse. It was working on Macs from very early time and remember even reading about it somewhere. Then it was lost.
The rewrite is better! For the engineers who are planning to have a new job in a year. They get a whole year of being able to deflect all questions about how far behind schedule we are and how many of the customers want to burn the building down.
It's a great gig if you can get it. Horrible for the users and investors, of course, but great for the engineers.
Relatedly, my immediate reaction was "tooltips on logos? Just use alt attributes and browser native tooltips, stop reinventing wheels that are already decently handled in HTML".
