The proficiency bar is full, and I continue to answer questions correctly, but I'm not getting the proficiency popup or any other message related to it. I do still get points, and that does pop up.

Visiting the dashboard shows that I have proficiency for this exercise.

I'm seeing the following message in my js log:
Uncaught TypeError: Object #000 has no method 'getTotalLength'

I'll leave the window open and monitor this bug in case there's any other information I can provide that might be helpful.
