with a dot

* Author: cpinto (Celso Pinto)

* Priority: Normal
* ruby -v: ruby 2.7.7p221 (2022-11-24 revision 168ec2b1e5) [arm64-darwin22]
* Backport: 2.7: REQUIRED, 3.0: REQUIRED, 3.1: DONE
----------------------------------------
The rspec tests of our Rails app started failing with an ArgumentError after upgrading to
2.7.7. On inspection, the issue seems to be caused by CGI::Cookie.domain=:
```
def domain=(str)
if str and ((str = str.b).bytesize > 255 or !DOMAIN_VALUE_RE.match?(str))
raise ArgumentError, "invalid domain: #{str.dump}"
end
@domain = str
end
```
Setting a breakpoint:
0> str
=> ".example.com"
0> DOMAIN_VALUE_RE
=> /\A(?<label>(?!-)[-A-Za-z0-9]+(?<!-))(?:\.\g<label>)*\z/
0> DOMAIN_VALUE_RE.match?(str)
=> false
0> DOMAIN_VALUE_RE.match?('example.com')
=> true
