When there are available gaps but not long enough for the whole appointment, it shows the day as available but not bookable

[Valentina R]

To reproduce, set the product duration to 45 minutes, padding to 15 minutes, and interval to 60 minutes. Availabilit from 14:00 to 17:00.

If you book all 3 slots via the website (14h, 15h, 16h), the day is unavailable.

But if you add availability rules (gCal events) that last 45 minutes (14:00-14:45, 15:00-15:45, 16:00-16:45), the day shows as available but no slots to book. It should show as unavailable.
