I've hit that browser bug too.  I think adding a space of text content 
between the script tags is also helpful on some browsers, and a 
convenient workaround to the issue you have here.

Semantically the expanded and unexpanded forms are identical.  You're 
just trying to work around browser bugs.  We have the 
expandEmptyElements() option specifically for this.

It's <br> and </br> actually, which a decent browser shouldn't see as 
two breaks.  Argh.

No one's bothered with an HTMLOutputter yet.  For you adding a space in 
the script element and leaving empties unexpanded would fix the issue.
