Thanks for the update Maxim.
Marshall, his commments enhances my opinion about this.
If you want to use javascript to render some html do it in a seperate
controlled environment (e.g. rhino) and inject the actual html out to VPE
when it is done.

1)For know we are not support execution of java script in visual editor.
To allow javascript we should switch off design mode, but know it's
hard to do, because all selections events
processing throw nsISelectionController which can be obtained only
if we switch mozilla in design mode.
2) possibly JavaScript that inserted into head node doesn't be executed
automatically, because browser executes this scripts
when documents are loaded. When we insert it into DOM, document already
loaded.
PS. Using of JavaScript in Visual Editor can strongly change the process
handling, because we can modify dom using js, and using
xpcom, there then many questins how to map elements from source and
visual part and others.
