Dropdown problem displaying results twice

Description

Issue Key: CR‌-205
Reporter: Allyson Pyers

Some MITx learners have reported a dropdown problem displaying the answer choices twice. (showing "x(t) x(t)" when the answer should be "x(t)"). A learner and a community TA have reported the issue on this forum thread, and a screenshot of the issue is attached.

The issue was reported on the first problem of this course unit:

https://courses.edx.org/courses/course-v1:MITx+18.01.1x+2T2018/courseware/unit2/diff_1-sequential/3

The learner and community TA have reported the issue in Edge and Chrome. The course team and I have not been able to reproduce the issue.
