Mobile Design Course Bug

Hello,

I am currently about to start the Final Exam for the Mobile Design course, and when I click continue learning (96%), it functions properly by bringing up the amount of XP available to be earned with a start button; however, I clicked enter instead of using my mouse to start the quiz, and it brought up the same modal again. The screen got brighter with every press of the "enter” button on the keyboard and the modal would overlay the first one with every press. Just to confirm this was an error, I clicked the “X” button which closed one modal at a time requiring me to wait for the “X” hover/click animation before closing each prompt. I figured this could confuse less advanced users, especially given many courses include and/or involve UI/UX design & development. Thanks for reading my insight. Take care.
