Domain update fails for constant values

The domain updates, or precisely _check_range method, throws an error in https://gitlab.renkulab.io/ai-augmented-design/aixd/-/blob/master/src/aixd/data/domain.py#L366 when the values in a given (typically performance attribute) variable are the same.

File ~\CODE\aixd\src\aixd\data\domain.py:366, in Interval._check_range(self, min_value, max_value)
    364 """Checks if the given range is valid. Raises an error if not."""
    365 if min_value >= max_value:
--> 366     raise ValueError("The min value must be smaller than the max value")
    368 if self.type == "integer":
    369     min_value, max_value = int(min_value), int(max_value)

ValueError: The min value must be smaller than the max value

Seems to point to thw way min-max is calculated or updated in _check_domain_consistency: https://gitlab.renkulab.io/ai-augmented-design/aixd/-/blob/master/src/aixd/data/domain.py#L463-481
