Since a recent thunderbird update I cannot send messages with a custom header

I have a custom header X-TTS: configured as "mail.compose.other.header;X-TTS" when I try and send a message with something in that custom header nothing happens when I click the send button it just responds like I hadn't clicked it. No error messages no nothing.

If I remove the contents from the custom header then the send button works and is able to send the message.

I reverted to 78.5.1 from 78.6.1 and the custom header works in that older version.

I don't know if this is a separate bug, but there has been some discussion about custom headers being lost after saving as a draft:

It maybe related to the ongoing development of the new addressing routine.

Thanks I will mention this in the bugzilla ticket.
