227870 - Save as '.EML' can corrupt HTML attachment's CSS style block

Status: RESOLVED DUPLICATE of bug 339595

(MailNews Core :: Backend, defect)

Description

[Mike Cowperthwaite]

Receive a message containing an HTML attachment, which has a <style> block such 
as this (with no indentation in the block):
======cut======
<style>
.demo { color: red; }
</style>
======cut======

If this message is saved as an EML file, the text of the saved file has the 
initial '.' stripped off the selector ".demo" so that the style rule is now:
======cut======
demo { color: red; }
======cut======

This causes any text that would use the .demo rule to lose its styling.

Discovered this while testing for bug 174692.  Symptom present in 1.5Final and 
1.6b-1120.

Attachment: Simple HTML file that demonstrates bug

Download and save this file, then compose a message with the file as an
attachment.  (Send it, or save as a draft.)  Save the message as a .EML file;
drag the EML file to the browser and see that the rendered version of the HTML
attachment does not have red text.

hange 'eml' in summary to '.eml' for ease of search ('extremly' will hit).
