Dynamic script execution wont work as of FireFox 2.0.0.2 The script (see steps) did work prior to FireFox 2.0.0.2 and does work in IE7 (and earlier) and Opera 9.10 (and earlier).

It looks like the dynamic script is not executed synchronously anymore!

Reproducible: Always

Steps to Reproduce:
1. Create an file with the following content:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="nl">
    <head>
        <title>Dynamic Script Test</title>
        <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
        <script type="text/javascript">
            var gsScriptId = '__eval_script__';

            var evalScript = function(psScript) {

                var oScript = document.getElementById(gsScriptId);
                try {
                    if (oScript) {
            		    oScript.parentNode.removeChild(oScript);
                    }
                    oScript = document.createElement('script');
        		    oScript.setAttribute('type', 'text\/javascript');
        		    oScript.setAttribute('id', gsScriptId);
        		    oScript = document.getElementsByTagName('head')[0].appendChild(oScript);
        		    oScript.text = psScript;
                }
                catch(e) {
                    throw Error('Unable to evaluate "' + psScript.substr(0,10) + '..." ->' + e + '.');
                }
                finally {
                    if (oScript && oScript.parentNode && oScript.tagName == 'SCRIPT') {
            		    oScript.parentNode.removeChild(oScript);
                    }
                }
            };

            var init = function() {
                evalScript('function testScript(){window.alert(\'YES!\');}');
                testScript();
            };

            window.onload = init;
        </script>
    </head>
    <body>
    </body>
</html>

2. Run it in FireFox 2.0.0.2

Actual Results:  
Error message indicating that the function 'testScript' does not exist. 


Expected Results:  
It should display 'YES' in a message box.
Version: unspecified → 2.0 Branch
Regression range for this on 1.8 branch is 2007-01-16 03 - 2007-01-17 03.
I see it also in 1.8.0.

Similar testcase and same regression range as bug 371576, so probably a dup.
