Description BJ Burg 2015-12-04 10:28:05 PST 
STEPS TO REPRODUCE:

1. Set a breakpoint and pause somewhere
2. Hover over a token to show the popover
3. Without mousing over the popover, quickly move to highlight a different token


EXPECTED:

 - Popover repositions with a short animation

ACTUAL:

 - Popover's previous position and size is reused



NOTES:

This is especially annoying when the previous position is very small and the new size should be very large. See the attached video.

It seems that when the popover direction (i.e., position of bubble relative to token) is the same between two hovers, the position and size are reused. If the direction differs, the popover is correctly repositioned.
