BCC loses entry when email saved dlp

[dlpcap]

TB 78.4.0

When I put entries in BCC section of an outgoing email, then save the email to send later - when I open it to send, the 2nd entry disappears each time, and I have to re-enter that entry before sending.

Got any ideas what's going on? It's very tedious to have to keep checking to make sure all of the BCC's are being sent!

I wasn't able to reproduce this using TB 78.4.0 on Ubuntu 18.04 LTS Linux.

The 2nd Bcc was slightly hidden, and there was a scrollbar in the address area that I used to scroll down and completely reveal it.

I would suggest trying safe mode using Help > Restart with Add-ons Disabled to see if an extension is causing the problem.

I only used 2 Bcc addresses. So if you are using more and the 2nd one always disappears then please state that in a reply.

I noticed this on further testing: I generally have a group email as first entry in the BCC section. It is then when the 2nd standalone email disappears on saving.
Further, no matter where I put the 'group' email entry, the standalone entry following disappears. Interesting?

Confusing is more like it.

By group, you mean a mailing list with numerous addresses in it, then a single email address to one recipient following that in the Bcc field, or any address field?

This will be fixed some time AFTER 78.5.0 https://bugzilla.mozilla.org/show_bug.cgi?id=1674650
