fix: release pointer capture when using onPointerLeave events

Certain input sources (such as touch) are "captured" when they
press an element. This means the pointer is always considered
"inside" the element by the browser, even when they visually are
not. This caused some issues on mobile browsers where touch and
stylus events could not connect table columns with each other.

Just to be safe, I've added the required `releasePointerCapture`
call everywhere `onPointerEnter` or `onPointerLeave` is used.
