<ul>
<li>Select the entire contents (Ctrl + A)  of the textbox (large buffer)
<li>Hit the delete key
<li><a href="javascript:save(1);">CLICK Here</a>
<li>Notice,  the first alert box  should show that the value of the node is blank.  Hit Enter
<li>This alert box,  will start with 'jesse'  (the value i assigned in the javascript)  followed by a portion of the buffer that was originally a part of the node.

Jesse, can you confirm this works on trunk for you?

http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/
Whiteboard: WFM on trunk?
That worked for me.
Resolving this bug as WORKSFORME since we're not sure what checkin fixed this. This will be fixed in Firefox 3.
