Allows marquee to behave as a block level element.
*** Bug 153983 has been marked as a duplicate of this bug. ***
Didn't we already fix this in bug 147183?
simon, the other fix does not address the parser problem. 
jaimejr, this is the bug we really need to get into MachV. According to harishd,
the patch should have no risk for page which do not have <marquee> tag init. 
Keywords: intl, nsbeta1
This fix is also needed if we have the following
if we want to find the first childrean of the marquee through DOM, without this
patch, it won't find the div. That is violation of the DOM spec. 
The fix move the treatment of <marquee> in the html parser code from one
undefined behavior to aonther undefine behavior in term of html (change from
inline to block). But it fix the DOM problem according to the DOM specification. 
Also, it is very very very very important for one of our top embedding issue.

patch v1.0

What kind of element class do we end up creating for this new tag?
nsHTMLUnknownElement? If so, we won't get any inline style on these marquee
elements, and that would probably be a bad thing, no?

IOW, don't we need to hook the sink up to create some more sane type of element
class for marquee elements? Maybe just a div (i.e. a nsHTMLDivElement with the
name "marquee") would be good enough, or do we need more than that?

sr=jst for the parser changes at least.

jst: thanks for your sr=. Let's focus one thing at a time. I think marquee
defined by some other company as block instead of inline. But that is an
seperate issue. 
heikki- can you r= this one? this is one of the top priority now. thanks.

We end up creating NS_NewHTMLSpanElement element!. I'm not sure if that's a bad
thing or not. But, you're right may be we need to create nsHTMLDivElement if
marquee really wants to behave as a block.
