It seems that when a commit is added to an approved PR, only the reviews of write-allowed reviewers are automatically dismissed.
Example: eclipse-score/.eclipsefdn#147
- PR created
- PR approved by project lead
- PR approved by eclipsefdn-security member
- commit pushed
- approval of eclipsefdn-security member automatically dismissed
- PR is still eligible for auto merge, as it remains approved by project lead
