viewing a user with a file user picture deletes the field value

Problem/Motivation

I just did a migration of a D7 site to D10, with this module enabled. Some of the users have user pictures, uploaded as files.

Every time I view a user at user/xxx, the user picture field value for that user is deleted.

AFAICT this is caused by the avatar module.

Steps to reproduce

Proposed resolution

Remaining tasks

User interface changes

API changes

Data model changes
