1. Explicit type of e parameter is redundant.
2. For runtime safety, please consider type assertion instead of casting.

Suggested change

	onWheel={(e: WheelEvent<HTMLInputElement>) => {
	// Prevent changing value by mouse wheel
	if (e.target === document.activeElement) {
	(document.activeElement as HTMLInputElement).blur();
	}
	}}
	onWheel={(e) => {
	// Prevent changing value by mouse wheel
	if (
	e.target === document.activeElement &&
	e.target instanceof HTMLElement
	) {
	e.target.blur();
	}
	}}
