Build ID: 20120601045813

Steps to reproduce:

To start, while While viewing an item in an RSS subscription folder, change the setting View -> Feed Message Body As -> { Original HTML, Simple HTML, Plain Text }.


Actual results:

Nothing.  The message view remains the same regardless of that setting.


Expected results:

Should be able to see a difference between HTML and Plain Text modes.

I discovered that I could get the desired result by going to a mail message, changing View -> Message Body As, then go back to the RSS item.

The difference seems to be between mailnews.display.html_as and rss.display.html_as.  Which setting changes depends on what you're currently looking at, but only the mailnews version has any effect, on both types.

I can confirm this with manual tweaking in about:config too.  (Requires clicking away from the item and back to effect changes.)  Altering rss.display.html_as does nothing, but altering mailnews.display.html_as has the desired effect even on rss items.

As you can see in the code here: http://mxr.mozilla.org/comm-central/source/mail/base/content/mailWindowOverlay.js#423 the rss.display.html_as pref is used in the menu item depending on if the message is a feed msg. But according to this: http://mxr.mozilla.org/comm-central/search?string=rss.display.html_as&find=&findi=&filter=^[^\0]*%24&hitlimit=&tree=comm-central it does not seem to be read at any relevant spot when rendering a message (e.g. in mime as mailnews.display.html_as is: http://mxr.mozilla.org/comm-central/search?string=mailnews.display.html_as&find=&findi=&filter=^[^\0]*%24&hitlimit=&tree=comm-central) .

Either this belongs into Message reader UI or in Mime component .
