fix: addEventListenerWrap param target may be nullish

[zerosrat]

When target is nullish, it will throw TypeError: Cannot read properties of null (reading 'addEventListener').
So I add the optional chaining to avoid the error.

It's strange to provide empty as target. But this code seems fine.

It's strange to provide empty as target. But this code seems fine.

The origin issuse is from stickyScrollBar of rc-table. The code is as follows:

React.useEffect(function () { var onMouseUpListener = addEventListener(document.body, 'mouseup', onMouseUp, false); }, [])

When invoking addEventListener in useEffect, document.body is null. Add null check can avoid the error log, but it still cannot add listener as expected.
