This is working as intended.

Dao, could you please elaborate why this issue seems invalid to you? In the comment 0 scenario, the element border persists even though it shouldn't.
As a side note, this behavior is not reproducible on Chrome, Safari or IE.

Changing the bug title for a better understanding of the issue.
