etc). Submit multiple pull requests if needed. -->

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

Currently, if you're using voiceover on Chrome or Firefox, you can
navigate the checkbox in such a way that it announces the checkbox
image, which provides no context to what you're actually selecting.

## What is the new behavior?

this PR. -->

With this change, you can no longer select the checkbox image.
