1682577 - outlook html-message is broken when forwarding from TB 78

Status: RESOLVED DUPLICATE of bug 1681365

(Thunderbird :: Untriaged, defect)

Description

[Alexey]

Attachment: Outlook message.eml

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:83.0) Gecko/20100101 Firefox/83.0

Steps to reproduce:

Forward HTML-message generated by Outlook.
Sample message is attached.

The message should contain in it's source-code, in HTML part following section:
<style><!--
/* Font Definitions */
...
--></style>

Actual results:

Forwarded message loses HTML comment closing tag "-->" in the section:

<style><!--
/* Font Definitions */

before </style> closing tag

This leads to incorrect HTML-rendering and as consequence to incorrect message displaying in CommuniGate web-client.

Expected results:

Comment closing tag "-->" should not be lost, so that HTML-code was rendered correctly.
It was noticed, that the described issue arose in Thunderbird 78 and is not produced in Thunderbird 68.
