The new editor always make it seems the template changed, even if there is no actual change.

Result - we are unable to change assignment of locked templates

Can you provide steps / screenshots on how to reproduce this bug?

Discussed offline, but for consistency:

Problem is editor is sending the content even though it hasn't changed (and is actually readonly).
