Wil,

I can readily reproduce no matter how I exit annotation mode, whether with three-finger tap, stylus-touching the top left X, or pressing the physical back button on the tablet.

I did find that if I enter annotation mode by touching the screen with the stylus, I can reproduce a lot more readily than if I enter with a three-finger-tap. And exiting with the three-finger tap does seem to cause it somewhat more reliably than the other exit methods (and it doesn't make a difference whether the stylus is in my hand).

Just to be sure it wasn't actually a split-second tool-switching issue, I also set the two-finger-tap action to None, and found the same results.
