1744479 - Save as HTML does not include header information

Status: RESOLVED DUPLICATE of bug 1738031

(Thunderbird :: Untriaged, defect)

Description

[Peter]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:94.0) Gecko/20100101 Firefox/94.0

Steps to reproduce:

Select message
Right-click message
Choose Save As...
Select Save as type: HTML Files (.html;.htm;.shtml;.xhtml)
Save file

Actual results:

File saved as HTML does not display basic header info, e.g. Subject, From, Date, To fields. I am seeing this behavior with Thunderbird 91.3.2 (64-bit).

I've also opened a saved HTML message file with Notepad++ and see no evidence of the header fields within the file. So this is not a display issue with the saved messages but a change to what is saved into the HTML message files.

Based on checks I've made of recently saved messages, this behavior apparently surfaced sometime after 9/13/2021.

Expected results:

HTML files should display basic header header info, i.e. the same info displayed when saving as Text Files (.txt;.text) or Mail Files (*.eml). This information is very important from an archival and documentary standpoint, which is my reason for saving as HTML in the first place.
