waiting_state and start_time { entity } config showing "Invalid Date"

[gwilford]

Describe the bug "Invalid Date" is displayed instead of the start time while in waiting state:

Bosch Dishwasher - Operation state         Delayed Start Invalid Date

Both start_time and end_time entities are defined and are of type device_class: timestamp:

2024-03-12T00:06:39+00:00
2024-03-12T02:25:06+00:00

Is the start_time entity config being ignored or overriden by the main entity state/start_time attribute?
