It looks like this came in under a commit on LSNBLDR-723, not sure if this was intentional or a bug. The comment on the line is
As an instructor, you can create a question in lessons and submit an answer multiple times. There is no way to remove the submitted answers.
Steps to reproduce:
As an instructor, go to Lessons
Click Add Content, then choose Add Question.
Create a multiple choice question with possible answers, Click save.
Go to the question, and show poll. It should be 0 for everything.
Then choose an answer, click submit, show poll.
Instructor can then submit again, even though the Submit button is grayed out.
The poll will continue to record submitted answers from the instructor, but cannot be removed
