Not open first tab directly on mobile devices

When scrollToAccordion is set to true you jump directly to the open tab on mobile devices. So a check was added to only open the first tab when the actual device is not a mobile.

} else if (!window.matchMedia('(max-width: 646px)').matches) {

you wrote:

} else (!window.matchMedia('(max-width: 646px)').matches) {
