I just started the course and noticed a bug in the quiz at the end of the chapter 2. Here are the steps to reproduce it:

1. Enter the End-to-End chapter quiz.
2. Click on Tensorflow.
3. Complete the quiz.

Expected result: After completing the quiz, the “completed chapter” button should activate, allowing you to click on it.

Observed result: After completing the quiz, you can’t click the button “completed chapter” .
