As we've discussed offline, this counter is for tap only, so we shouldn't be
using that.

I think we could use the getPromoOpenCount(), but that will only work if the
user is undecided (we only update the count if the promo is showing, which
happens when the user is undecided).

If the logic is that we should show it for long press only if the user has never
opened the panel before that would be OK since if the user has never opened the
panel, then the user must be undecided (can only decide after opening the
panel).

In either case, please write down some comment explaining this logic and why we
are reusing the PromoOpenCount, which is not immediately obvious to an
uninformed reader.

Done.
