whenever use zypper --repo (-r) switch it ignores

for example, with non-existing repo:

zypper se -r 123

returns all packages from all repos, so any search with -r <alias|name|#|URI>
switch doesn't work too

expected behavior:

zypper should return:

Repository '123' not found by its alias, number, or URI.
Use 'zypper repos' to get the list of defined repositories.


or return package list from specified repo
