Weird Date range with time when spaning multiple days

To reproduce set the duration & interval to 135 min (or anything else). Set the availability of the product with “Date range with time” 31.12.2023 18:15 - 01.01.2024 01:00. The expected behavior is to have slots at 18:15, 20:30, and 22:45. But the last slot doesn’t exist. If you change the rule to 31.12.2023 18:15 - 31.12.2023 01:00 all three slots will be visible.
