terraform import esxi_vswitch.test test followed by terraform plan/apply does not seem to work

[rgl]

Describe the bug

Doing a terraform import esxi_vswitch.test test followed by terraform plan/apply wants to re-create the vswitch.

To Reproduce

Steps to reproduce the behavior:

1. terraform import esxi_vswitch.test test
2. terraform plan/apply

Expected behavior

Expected a noop plan after an import.

Terraform file

resource "esxi_vswitch" "test" {
  name = "test"
}

Desktop (please complete the following information):

• OS: Ubuntu 20.04
• Terraform Version: 1.0.7
• This Plugin Version: 1.8.3

Additional context

Here's a transcript:

# see that the vswitch does in fact exist, because it fails to be created by terraform without a previous terraform state.
vagrant@ubuntu:~/test-terraform-esxi$ terraform plan -out=tfplan

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated
with the following symbols:
  + create

Terraform will perform the following actions:

  # esxi_vswitch.test will be created
  + resource "esxi_vswitch" "test" {
      + forged_transmits    = (known after apply)
      + id                  = (known after apply)
      + link_discovery_mode = (known after apply)
      + mac_changes         = (known after apply)
      + mtu                 = (known after apply)
      + name                = "test"
      + ports               = (known after apply)
      + promiscuous_mode    = (known after apply)
    }

Plan: 1 to add, 0 to change, 0 to destroy.

────────────────────────────────────────────────────────────────────────────────────────────────────────────────

Saved the plan to: tfplan

To perform exactly these actions, run the following command to apply:
    terraform apply "tfplan"

vagrant@ubuntu:~/test-terraform-esxi$ time terraform apply tfplan

Import successful!

The resources that were imported are shown above. These resources are now in
your Terraform state and will henceforth be managed by Terraform.

# plan the changes, and notice it tries to re-create the vswitch, but it shouldn't.
vagrant@ubuntu:~/test-terraform-esxi$ terraform plan -out=tfplan
esxi_vswitch.test: Refreshing state... [id=test]

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated
with the following symbols:
-/+ destroy and then create replacement

Terraform will perform the following actions:

  # esxi_vswitch.test must be replaced
-/+ resource "esxi_vswitch" "test" {
      ~ forged_transmits    = false -> (known after apply)
      ~ id                  = "test" -> (known after apply)
      ~ link_discovery_mode = "listen" -> (known after apply)
      ~ mac_changes         = false -> (known after apply)
      ~ mtu                 = 1500 -> (known after apply)
      + name                = "test" # forces replacement
      ~ ports               = 128 -> (known after apply)
      ~ promiscuous_mode    = false -> (known after apply)
    }

Plan: 1 to add, 0 to change, 1 to destroy.

It seems the import does not set the vswitch name inside the terraform state:
