audit_log_include_accounts does not work using IP addresses

The problem of https://bugs.mysql.com/bug.php?id=77553 is still present.
If I try to set audit_log_include_accounts or audit_log_exclude_accounts variables, they work with user@localhost but they don't work with user@127.0.0.1.

When
set global audit_log_include_accounts = 'user@localhost';

There was the audit for each action depending audit_log_policy
"Connect","6078172_2017-02-09T17:06:19","2017-02-10T08:17:20 UTC","1699",0,"user","user","","''@''","localhost","",""
"Quit","6078173_2017-02-09T17:06:19","2017-02-10T08:17:22 UTC","1699",0,"user","user","","''@''","localhost","",""

When I've tried one of the set below
set global audit_log_include_accounts = 'user@127.0.0.1';
set global audit_log_include_accounts = "'user'@'127.0.0.1'";
set global audit_log_include_accounts = '\'user\'@\'127.0.0.1\'';

There was nothing the audit.

Vice versa, when
set global audit_log_exclude_accounts = 'user@localhost';

There was nothing the audit.

When I've tried one of the set below
set global audit_log_exclude_accounts = 'user@127.0.0.1';
set global audit_log_exclude_accounts = "'user'@'127.0.0.1'";
set global audit_log_exclude_accounts = '\'user\'@\'127.0.0.1\'';
