I couldn't reproduce that.
In Firefox 2:
javascript:s='<?>';for(i=0;i<1006;++i)s+='
';window.location='data:text/html,'+s+'<!doctype
html><script>document.write(document.compatMode)</script>'
javascript:s='<?>';for(i=0;i<1007;++i)s+='
';window.location='data:text/html,'+s+'<!doctype
html><script>document.write(document.compatMode)</script>'
The first produces CSS1Compat, the second BackCompat. As far as I can
tell, Firefox requires the doctype to be found when parsing [using
standards-mode rules] the first 1024 characters (not bytes) from the
first non-whitespace character, and then it reparses the whole
document in quirks mode if necessary.
