[useMouse()] mouse.y is off by 0.5 and shows as -0.5 when at the very top of the tracked element

[c0dezer019]

Describe the bug
Regardless of position, position increments as 1 and starts at 0.5, so 1.5, 2.5, 3.5 etc. Will track to -0.5 before pos value is set to none (when mouse is slightly just above the element).

To Reproduce
Steps to reproduce the behavior:

1. Setup a div as specified in the instructions. Add <p>x: {mouse.x} y: {mouse.y}</p> to display pos within element.
2. Start from the top
3. Move mouse down the tracked div.
4. Reverse steps.

Expected behavior
y is not offset by 0.5 and that the numbers either freeze (preferably freeze) or not displayed when pos is exactly 0.

Additional context
Done with Next.JS and on a styled-component element. Not sure that this would be a cause though.
