Radio button flickers when chosen a wrong option #3263

Closed pravesh00 closed 3 years ago

pravesh00 commented 3 years ago

Describe the bug The radio button in practise mode flickers or we can say all options refreshes every time we select a wrong option. Also, I think it would be good to have an immediate reflection to the user that the option was correct or wrong by highlighting the selected radio button as green or red for like 500ms to 1000ms.

To Reproduce Steps to reproduce the behavior:

  1. Go to Practise Mode
  2. Click on the wrong option of question
  3. See the options refreshes every time

Expected behavior Only the wrong radio button selected should reset.

@pravesh00 That looks like a flicker but thats because on selection of incorrect answer, one item is getting added to the entire list of items. In your video you can notice that the count in Previous Responses increases as soon as you click as the SelectionInteraction gets added again at bottom.
