Event_Session and Event_Sale_Session, not reflecting Sessions choices on Website in 14 Branch

[l-arnold]

Is your feature request related to a problem?
Just implemented Branch 14 event_session and event_sale_session.
I cannot get a choice of Sessions to show up in the Website Event Booking.
It does show up and work in the backend

Describe the solution you'd like
Ideally, it would seem a session would be like an "variant" of a regular product, but here a "variant of an event".
The online user should be able to select available sessions.

Describe alternatives you've considered
It seems a Web Form that added the additional Session Choice would suffice, but need to add the field to an Event Web form.

Additional context
I note also that the views in Branch 15 are much expanded. Perhaps there is something there that can be backported.

It is really critical to function to get this to work.
I will test on a "Fresh Install" but expect I will have the same result.
Wanting to help further but in learning mode for now.
