Comment (by coderste):

 Regarding the issue @ocean90 pointed out. I believe this is because when
 you `hover` on an item that is active there is no `CSS` inside the `@media
 screen and (max-width: 600px)` for an active tab therefore it is using the
 desktop `CSS` which is using a `border-bottom: 1px solid #f1f1f1;` on
 `hover` hence it removing the bottom `border`.

 I have attached a patch that fixes the issue but if it doesn't relate to
 this ticket I will create a new one :)
