Nested Test.only are ignored

I really like to use Test.only when doing test-driven development, and I relatively often end up with nested Test.only (one on a describe and another one on a test inside it.

When this happens, the Test.only on the individual test is ignored, and the only one that is taken into account is the one on the describe, which is quite annoying.

SSCCE

module A exposing (tests)

import Expect
import Test exposing (..)


tests : Test
tests =
    describe "All tests"
        [ Test.only <|
            describe "Only tests"
                [ Test.only <| test "is correctly run" <| \() -> Expect.equal 1 1
                , test "is run but SHOULDN'T" <| \() -> Expect.equal 1 2
                ]
        , test "is correctly skipped" <| \() -> Expect.equal 1 2
        ]

This runs tests "is correctly run" and "is run but SHOULDN'T", though I would expect it only run the former test.

Start with the SSCCE in module A and run it through the node-test-runner test workflow to reproduce the nested Test.only behavior. Trace the handling of Test.only selections and verify that the completed behavior runs only “is correctly run,” while skipping “is run but SHOULDN'T” and “is correctly skipped”.
