google_dns_record_set always wants to update TXT records that are not escape-quoted

[abevoelker]

Terraform Version

Terraform v0.11.1
+ provider.google v1.4.0

Affected Resource(s)

• google_dns_record_set

Terraform Configuration Files

resource "google_dns_record_set" "foo" {
  name = "example.com."
  type = "TXT"
  ttl  = 300
  managed_zone = "foo-zone"

  rrdatas = ["foo"]
}

Debug Output

https://gist.github.com/abevoelker/e35529ee72f8b0619a9cae0130c8ce03

Panic Output

N/A

Expected Behavior

After the initial terraform apply, subsequent terraform plan operations should say "No changes. Infrastructure is up-to-date."

Actual Behavior

terraform plan continually wants to update the DNS record.

Steps to Reproduce

1. terraform apply
2. terraform plan

Important Factoids

I can work around the issue by escape-quoting the value (rrdatas = ["\"foo\""]), however the documentation makes it sound like that should only be required for values with spaces in them.
