Steps to reproduce:
- install Email Marketing
- duplicate an existing demo template
- edit > drag a block from the editor onto the email
Issue:
`Traceback: Uncaught Promise > Cannot read properties of undefined
(reading 'droppable')`
This happens because the email templates are not editable, which means no dropzones can be attached to them.
Solution:
Add classes 'oe_structure' and 'o_editable' to one div in the
templates so that at least one dropzone can be created.
