Returns true if this form is being loaded by a client Javascript service worker. This will be true when the
form is configured within a PWA as the start form or as an offline resource and is being loaded so
that the page HTML and any associated web resources can be cached on client devices by the service worker.
Typically this method would be used to control initialisation of the form and/or first page so that the correct page is returned to
the service worker to be cached.
