1671227 - Rendering of HTML newsletter changed

Status: RESOLVED DUPLICATE of bug 1659362

(Thunderbird :: Untriaged, enhancement)

Description

[Uwe Trenkner]

Attachment: HTML rendering in Thunderbird 78.3.2

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:82.0) Gecko/20100101 Firefox/82.0

Steps to reproduce:

Opening a HTML newsletter created using the MJML framework, which ensures appropriate look on a very wide variety of mail apps and webmailers.

Actual results:

With the upgrade to 78.3.2 (from 68.x?) the rendered HTML looks different, not good anymore.

Expected results:

If the screen width allows, the image should be shown left of the article summary. It did so in earlier versions of Thunderbird and still does in Firefox and other HTML rendering clients. Now it is moved to the top, as it should be when e.g. the screen size is too small.

This is how the newsletter should look like when screen is wide enough. It does so in most email apps. The rendering of Thunderbird changed.

There's a pref you can set to re-enable media queries. See bug 1659362

Thank you! And sorry, that I did not find that the bug was already reported... I was not aware of the cause (media queries) and thus searched generically for "html"...
