--fail-fast doesn't work with describe/test

[dandv]

Describe the bug

Passing --fail-fast to deno test is documented to stop on the first failure. This works with Deno.test(), but not with describe / expect.

Steps to Reproduce

main_test.ts:

import { describe, test } from '@std/testing/bdd';
import { assertEquals } from "@std/assert";

describe('addition', () => {
  test(function addTest1() {
    assertEquals(1 + 1, 42);
  });

  test(function addTest2() {
    assertEquals(2 + 2, 4);
  });
});

$ deno test --fail-fast
Check file:///home/dandv/deno-bugs/main_test.ts
running 1 test from ./main_test.ts
addition ...
  addTest1 ... FAILED (7ms)
  addTest2 ... ok (1ms)
addition ... FAILED (due to 1 failed step) (12ms)

 ERRORS

addition ... addTest1 => https://jsr.io/@std/testing/1.0.9/_test_suite.ts:393:15
error: AssertionError: Values are not equal.
[...]

Expected behavior

addTest2 should not have executed.

Environment

• OS: Fedora Linux 38
• deno version: 2.1.4
• std version: @std/testing@^1.0.9
