Is this a regression?

Yes

Description

Wrong warning in this case

Exemple : warning NG8102: The left side of this nullish coalescing operation does not include ‘null’ or ‘undefined’ in its type, therefore the ‘??’ operator can be safely removed.

{{element.CurrentLock?.Clinician?.Label ?? '--'}}

In this case CurrentLock and Clinician could be null
