Description
Guard asynchronous image decode and bitmap-cache results with the worker runtime epoch. Results that finish after reset/dispose are closed and discarded instead of being rendered or cached.
Motivation / related issue
A JPEG, PNG, compressed-depth, or bitmap conversion started before a seek or topic switch can complete after the worker is reset. It could previously repaint or cache a stale frame.
