Inconsistent :GoDoc behaviour

[XSven]

What did you expect to happen?

Pressing the "K" key on a given word that refers to a package name like "suite"

import (
  "github.com/stretchr/testify/suite"
)

should output the same as

:GoDoc suite

What happened instead?

:GoDoc suite that calls the shell command go doc suite (g:go_debug configured accordingly) provides more(!) documentation

...
func Run(t *testing.T, suite TestingSuite)
type AfterTest interface{ ... }
type BeforeTest interface{ ... }
type SetupAllSuite interface{ ... }
type SetupTestSuite interface{ ... }
type Suite struct{ ... }
type SuiteInformation struct{ ... }
type TearDownAllSuite interface{ ... }
type TearDownTestSuite interface{ ... }
type TestInformation struct{ ... }
type TestingSuite interface{ ... }
type WithStats interface{ ... }

:GoDoc with an argument delegates to go doc while K and :GoDoc without an argument delegates to gopls for speed. gopls returns slightly different information for some identifiers than go doc does.
