Also part of a trend to add more “hover and wait” elements pointlessly:

- Can’t see scrollbar without hovering and waiting.

- Can’t see folder drag icon in window title without hovering and waiting.

- Can’t interact with notifications without hovering and waiting.

- Can’t see full menu of options on Full Screen window button without hovering and waiting.

Dear Apple: this is a fundamentally backwards design trend that creates major productivity hits. These were arbitrary changes that made things harder to use. In short: there was no “design” happening here, it was just “fiddling”.
