When editing a multi-choice question type for a quiz. Under the hints there is a checkbox called "Clear incorrect responses" from the wording I would expect that when I click "Try again" after selecting an incorrect answer that the radio box of the incorrect answer was deselected.

Instead the hint is cleared and the form is re-enabled but the incorrect response is still selected.

Steps to reproduce:

• Setup quiz, make sure "How questions behave" under the "Question behaviour" heading is set to "Interactive with multiple tries"
• Add at least one multi-choice question with at least hint making sure the "Clear incorrect responses" checkbox is selected
• Preview or attempt the quiz, intentionally choosing an incorrect answer
• Click "Try again"
• The incorrect answer you chose should still be selected
