The selected radio button in a set of radio buttons is not preserved on a page reload via F5 if one or more form inputs have been dynamically inserted into the page before the radio button set.

Reproducible: Always

Steps to Reproduce:
1. Load testcase1.htm in the browser.
2. Reload the page via F5 three times.
Actual Results:  
After the first reload the Label 3 radio button in Radio Set 2 is selected.
After the second reload the Label 4 radio button in Radio Set 2 is selected.
After the final reload no radio button in Radio Set 2 is selected

Expected Results:  
The Label 2 radio button in Radio Set 2 remains selected.

Note in the second testcase what happens if two inputs are dynamically appended. The selected radio button in Radio Set 2 jumps two places down the set of radio each time the page is reloaded via F5.

I have run in to this problem as well. This can create some data corruption issues if the end users are not vigilant in double checking the data they are submitting in RIAs.

The test cases do a create job at recreating the problem.
