Thanks SuperSajuuk, that solution works for me.

(I had already noticed that moving the cursor away from the bell and back again worked, but hovering over "loading notifications" takes less time) Apparently when I was moving my cursor away, I was hovering over the "loading notifications" message for a split second, and triggering the notifications to load.
