The offset string format has changed from number concatenation to template literal with 'px' units. Ensure this change in format is compatible with the positionUtils.setup function, as it may expect unitless values or a different format.

Suggested change

	offset: `-${offset}px -${offset}px`
	offset: '-' + offset + ' -' + offset
