Steps to reproduce:

Forwarded an e-mail that contained an invite, adding additional message body text & website links to the forwarded message.

The invite in the forwarded message was accepted by the recipient.

They no longer saw the message body text.

Actual results:

The message forwards fine and the additional message body text can be seen as long as the invite is not processed or is not in the Calendar already. If the invite is processed/added to the calendar, the additional message body text is no longer shown and only the invite details are shown.

Expected results:

Ideally, the additional message body text that was added to the forwarded invite would continue to be shown, or have the option to be shown even if the invite is processed.

It is possible to view the missing message body text by disabling the calendar, or by viewing the "message source", but that requires more steps than should be needed, as well as potentially causing an important Calendar from being re-enabled.
