Having buttons (previously links) with the text "I agree 75%" is
confusing; people might believe they're saying they only partially agree
with the content. Besides, the results percentages is a different piece
of information which shouldn't be related to whether one person
agrees/disagrees with the content.
This problem might be solved for people using screen readers since we
added the aria-label attribute. However, for sighted keyboard users, the
percentage was being outlined on focus as part of the button, which
might be confusing.
