Cannot run tests when the root container is "When", but it works for its aliases ("Context" and "Describe")

[MaximeWeyl]

When the top container is a "When", the extension does not work. There is this error in the console :

Checking the Ginkgo executable was installed.
Ginkgo executable already installed. ;)
Checking the Ginkgo executable was installed.
Could not populate the outline view: TypeError: Cannot read properties of undefined (reading 'name')

But it works fine with "Context" and "Describe", which are aliases for "When".

Reproduction

This file demonstrates the problem :

package hive_test

import (
	"testing"

	. "github.com/onsi/ginkgo/v2"
	. "github.com/onsi/gomega"
)

func TestHive(t *testing.T) {
	RegisterFailHandler(Fail)
	RunSpecs(t, "Hive Suite")
}

var _ = When("Demo", func() {
	var s string

	BeforeEach(func() {
		s = "test"
	})

	It("should work with the extension", func() {
		Expect(s).To(Equal("test"))
	})
})
