Wrong tooltip position


as possible to see in the online demo, the tooltip position is not correct.
This happens when scrolling for two or three times from top to bottom of the page.
Here a screenshot:

I am using chrome version 89.0.4389.90

Thank you.

I have this problem as well. in my case it seems like it takes X coordinate correctly, but Y coordinate from the previous html elements position
hover over one

hover over 2, notice the Y position, it seems like it takes Y position from the previous html element tooltip hover

now hover over 1 element again

again the Y position
