paper-radio-group invalid attributes for ADA

[uxdesignz]

Actual Result:
The radio button group is a simulated UI widget that contains some invalid attributes. The information about the controls may not be communicated properly to screen reader users

Expected Results:
Remove the following attributes from the elements with role="radio":
• checked (this is meant for native HTML radio buttons and can interfere with the state being communicated properly to screen reader users)
• aria-selected (this attribute is not valid on an element with role="radio", the aria-checked attribute is used to communicate the state of the radio button)

Any update? when this issue will be resolved?
