Research direction

Start with shared/data/resources.js and getUserIdFromStore at line 136, using the linked Sentry stack trace as the reproduction clue. Trace how the undefined value reaches the tagName access and identify a project-supported way to reproduce it. Done means the Sentry TypeError no longer occurs and the relevant behavior is covered by an appropriate check.
