MCQ with 1 selectable answer and 1 or more attempts (not infinite), it is not possible to choose the same answer again after failing the component and resetting it.
Example: A question with answers A (correct),B (incorrect) and C (incorrect) and 3 attempts. User chooses answer B (incorrect), and fails. He then resets the komponent, but now he cannot choose answer B again.
Bonus fact, it is actually possible to select answer B, in the above example, if the user first chooses a different answer.
The same issue repeats on GMCQ.
