Attachment: Example HTML page with STYLE tag to use as attachment.

Maybe it's not to do with the style tag. I recently received an e-mail whose 1st
part was text/plain, and the 2nd was text/html. The text wasn't displayed but
the html part was (it contained an advertisment footer). The same mail was
displayed correctly under Netscape 4.76. I can send the message as an attachment
if you think it helps somehow.

This bug is actually pretty nasty. An HTML attachment seems to be able to
completely override the way a plain text message is displayed. That includes
style, background, etc. With proper "luck" leads to plain text message being
displayed black on black, or being all centered (instead on left-justified), or
being messed up in some other way.

P.S. I am currently running 1.6a/2003102323 on Fedora Core 1.

Confirming in Thunderbird 1.0 on FreeBSD and Windows XP.

1. Create a HTML document that contains a <link> to a stylesheet on the web
somewhere.  The stylesheet should contain body { color: #003366; } (or whatever
colour you happen to like).

2. Attach the HTML document to a plain text email and send it to someone, or
yourself.

3. View the email in Thunderbird.  The HTML attachment is displayed inline below
the plain text message, as expected.  However, the plain text message is
coloured by the style (fonts are changed too if the stylesheet specifies them).

Expected behaviour: the styling information should only be applied to the HTML
attachment.  The plain text message should be displayed as plain text.

I see this in Thunderbird too. I am guessing this should be in Product: Core.

I see the same error with HTML attachment without STYLE tag, but with a BODY tag
with BGCOLOR or TEXT parameters - the colors from them are used to display plain
text part of the message.

Attachment: Example of invisible text when forwarding HTML e-mail

On picture they are three steps: 1. original HTML e-mail, 2. forward window with invisible text (plain text) 3. texts becomes visible after selecting.

xref bug 341059. Would that be a proper solution to this problem?

[Mike Cowperthwaite]

I think this is a dupe of bug 31052.  See in particular bug 31052 comment 31.
See also bug 292336.

[Nobs Wolf]

this bug is still there in 2.0.0.21

is it really that complicated to fix?

just handle a HTML like an image; so it has an outer box in the UI where all positions are relative to

I guess the bug is, an embedded HTML gets the positional frame of the main body; it should be a nested one inside/below the main text

Quoting Stanimir Stamenkov from mozilla.support.thunderbird:

"but it might get resolved in future Tb versions once Bug 80713 "Need a way to specify an auto-height for an IFRAME such that the frame is given the full height of the contained content" <https://bugzilla.mozilla.org/show_bug.cgi?id=80713> gets resolved."

[Rich Pasco]

The problem is that when "view attachments inline" is enabled, a plain-text message gets displayed with the attributes of the attachment.  The attachment does not need a STYLE, it can be demonstrated when the HTML attachment specifies a body background color.  Same as Bug 31052.

This even happens in SeaMonkey Browser when viewing a message/rfc822 object containing an HTML attachment, see bug 524639 just duped to here.

I believe this is a dupe of bug 31052, see for example bug 31052 comment #9
