Bug 104873 – Validity of a radio button is not updated correctly when it is detached from an invalid radio group

• Component: Forms
• Status: RESOLVED FIXED

<form>
  <input type=radio name=g required id=radio2> 
  <input type=radio name=g required id=radio3>
</form>

If we remove radio2 from the document tree, it should update validity state and should be valid. However it becomes invalid.

Why do you need to remove const ?

Ditto.

You might want to also check that radio2.webkitMatchesSelector(":valid") is false before removing radio2.

RadioButtonGroup::m_member is a HashSet<HTMLInputElement*>
⇨ RadioButtonGroup::contains needs non-const HTMLInputElement*.
⇨ CheckedRadioButtons::isInRequiredGroup needs non-const HTMLInputElement*.
⇨ HTMLInputElement::isInRequiredRadioButtonGroup needs to be non-const.

Makes sense. Thanks for the clarification.
