On a page where I have some (2) radio buttons Javascript throws an "uncaught exception" when I try to loop through all the properties of either one of the radio button objects. In the loop it exception occured when it got to selectionStart and selectionEnd. If I just skip these two in the loop there are no problems. Secondly, I wonder why at all these two properties exist for radio buttons...

Reproducible: Always

Steps to Reproduce:
1. Go to the URL provided
2. Click the Test button which loops through all the properties of the first radio button
3. All property names are written to the screen and "OK" is added when access didn't fail.
Actual Results:  
Uncaught exception was thrown

Expected Results:  
The loop should complete without any problem.
