45781 - <div> inside <font> tags causes <p>s to render inline

Status: VERIFIED DUPLICATE of bug 42388

(Core :: DOM: HTML Parser, defect, P3)

Description

[Simon Fraser [no longer active]]

The BBC news site has some bad HTML that, however, renders fine in older 
browsers. It has something like:

<font ...>
<div>
<p>
blah
<p>
</div>
</font>

This HTML causes those <p>s to render as inline, rather than block elements.

This only appears to happen with the loose DTD. Testcase file is attached.

I believe this is the intended behavior of the Transitional DTD (triggered by
Transitional FPI with a System ID).

Changing component to HTML Parser and marking as duplicate of bug 42388, since
that's where the rest of these bugs are going.  I'm not sure if that's the best
thing to do with them, but it's better to have a uniform policy...

But this breaks backward compatibility with 4.x (which renders the pages just 
fine).

I know.  If you want to discuss it, see the (surprisingly quiet) thread "parser
and layout modes" on mozilla-layout.  Also see bug 42781.
