According to wikipedia: https://util.xat.com/wiki/index.php/Bump
You cannot bump someone unless they have you added, or you are a higher rank than the user.
Apparently, none of those conditions are applying on html5.
The bump will also work if somebody with lower rank than yours bumps you, as well as if the user is not in your friend list
2. Ask somebody you did not add as a friend or somebody with lower rank than yours to bump you.
3. The bump will work perfect, which should not be working.
