Requesting membership into a private group with comment doesn't save comment to DB

[scipi]

Navigating to a private group as a user and clicking on the Request Membership tab you are given the option of submitting a comment along with a membership request. This comment never gets saved to the wp_bp_invitations table and so the request.message token in the associated email event never gets filled out nor is the reason shown to group admins when they accept/deny the request.

Hi @scipi

Thanks a lot for your report. Good catch. I confirm the issue.
8359.patch is fixing it.

In 12719:

Make sure Group membership requests includes the optional message

When implementing the BP Invitations feature in 6.0.0, we forgot to set the content argument of the array passed to groups_send_membership_request()` function with the optional message content.

See #8359 (trunk)
