1182390 - Option "Return Receipt" lost if 'Edit as new' e-mail with "Disposition-Notification-To" in header in account with option "Return Receipt" by default

Status: UNCONFIRMED

(SeaMonkey :: MailNews: Composition, defect)

Description

[Rainer Bielefeld]

This one is a follow-up of “Bug 731112 - Return Receipt option (when composing mail) does not work”

Steps how to reproduce with with DE SeaMonkey 2.35(γ)  (Windows NT 6.1; WOW64; rv:38.0 nightly by Adrian Kalla)  Gecko/20100101 Build 20150616034436 (Classic Theme) on German WIN7 64bit:

1. Send email with activated option “return Receipt” from account with
   property “When sending messages, always request a return receipt”
2. In “Sent” folder of account you find a copy, click that e-mail-copy
   in Message Pane and then menu 'View → Message Source'
   » In source code as expected you will find header line 
      “Disposition-Notification-To: <your sender e-mail-address>”
3. For e-mail in sent folder: 'right click → Edit as new
  » Mail will be opened in e-mail Composer
4. click menu 'Options'
   Expected: checkmark at “Return receipt, because that was in sent 
             mail AND that is the default for that account
   Actual: no checkmark
5. Save Email as draft
6. In “drafts” folder of account you find a copy of your e-mail, click
   that e-mail-copy in Message Pane and then menu 'View → Source Code!
   Expected: In source code as you will find header line 
             “Disposition-Notification-To: <your sender e-mail-address>”
   Actual: Disposition-Notification header line is missing.

a) That seems to be a bug because that is not in accordance with 
   account settings “Always ask for return receipt”
b) Still the same  with  SeaMonkey 2.39a1 Mozilla/5.0 (Windows NT 6.1; 
   WOW64; rv:42.0 from official download area)  Gecko/20100101  
   Firefox/42.0 (Classic Theme) on German WIN7 64bit
c) Needs to be tested with Thunderbird.
