No membership tokens available in mailing

Overview

When selecting memberships using "find memberships" and drafting an email to them, I would like to have membership tokens like membership.fee available.

Reproduction steps

1. Click on Membership -> Find memberships.
2. Select some memberships
3. Create an email using the actions
4. Try to add a membership token

Current behaviour

No membership tokens are available and using them anyway doesn't work.

Expected behaviour

Membership tokens should be available for use.

Comments

My organisation is quite dependent on this feature for our yearly membership fees, so any help is appreciated.
