Merging props when using Popover2 renderTarget

Environment

Feature request

When using the renderTarget feature of Popover2 (specifically, I'm using Tooltip2), it is not clear which properties are actually used. For example, it seems that if you use {...tooltipProps} and then {className="my-class"}, the latter will overwrite the former and the bp2-popover2-target class will be lost.

Examples

        <Tooltip2
            content="my tooltip"
            renderTarget={({
                ref: tooltipRef,
                isOpen: _tooltipIsOpen,
                ...tooltipProps
            }) => (
                <Button
                    elementRef={tooltipRef as IRef<HTMLButtonElement>}
                    {...tooltipProps}
                    className="my-class" // !!! this overwrites property from ...tooltipProps !!!
                </Button>
            )}
        />
