Problem

Steep cannot find method definition if the parent module has the same name as the child's name.

Reproduce

steep check should not report any errors, but it reports an error.

$ bundle install
$ bundle exec steep check
# Type checking files:

............................................................................F.....

test.rb:4:6: [error] Type `(::Object & ::M)` does not have method `bar`
│ Diagnostic ID: Ruby::NoMethod
│
└       bar
        ~~~

Additional information

rbs method looks sane.

$ rbs -I . method M::M bar
::M::M#bar
  defined_in: ::M::M
  implementation: ::M::M
  accessibility: public
  types:
      () -> void

$ rbs -I . method M::M2 bar
::M::M2#bar
  defined_in: ::M::M2
  implementation: ::M::M2
  accessibility: public
  types:
      () -> void
