Firefox - some UI stuff happening recursively

[andrew-aaron]

Describe the bug On Firefox, dropdown menus containing hints will recursively open and close very quickly. This issue might be happening in the code editor as well, where it makes it impossible to continue or jump back to the lesson page.

To Reproduce Steps to reproduce the bug:

1. Use Firefox
2. Click on a dropdown menu like "Can you tell me more about that run() function?"

Expected behavior Click on the menu and simply see the hint.

Information about your device (please complete the following information):

• Operating System: Windows
• Browser: Firefox

Additional context If you click Run in a code example near the dropdown the dropdown will stop.
