This is incorrect. In the Firefox 3.0 development cycle we tried to  
change our implementation to match HTML 4, but had to revert due to  
breaking websites.

There is lots of good data in the bugs I cited. And suggestions for  
further reasearch.

If someone feels passionate about this I suggest they do the remaining  
research as well as getting the know broken sites fixed. *That* has a  
much greater chance of getting implementations to change than anything  
any spec says.
