HTML radio buttons should not require the user to click on the
actual circle, it should be enough to click on the label. Nitrogen
produces HTML that does not allow for this behaviour (at least not
in Firefox or Chrome):
<input name=".wfid_temp635285" value="1" type="radio" class="wfid_temp635323 wfid_myRadio1 radio" checked="true"/><label for=".wfid_temp635323">Option 1</label>
I would suggest that the generated HTML should be either:
<input name=".wfid_temp635285" value="1" type="radio" id="wfid_temp635323" class="wfid_myRadio1 radio" checked="checked"/><label for="wfid_temp635323">Option 1</label>
or:
<label for="wfid_temp635323"><input name=".wfid_temp635285" value="1" type="radio" id="wfid_temp635323" class="wfid_myRadio1 radio" checked="checked"/> Option 1</label>
or even:
<label><input name=".wfid_temp635285" value="1" type="radio" class="wfid_myRadio1 radio" checked="checked"/> Option 1</label>
