Order of test transforms influences flakiness of tests

[Gedochao]

This works:

//> using scala 2.13
//> using dep org.scalameta::munit:1.1.0

import munit.Tag

class CustomFlakyTests extends munit.FunSuite {
  override def munitFlakyOK: Boolean = true

  private val CustomFlakyTag = new Tag("CustomFlaky")

  override def munitTestTransforms: List[TestTransform] =
    List(
      new TestTransform(
        "Custom Flaky",
        { test =>
          if (test.tags.contains(CustomFlakyTag)) test.tag(munit.Flaky)
          else test
        }
      )
    ) ++ super.munitTestTransforms

  test("fail".tag(CustomFlakyTag)) {
    assert(false)
  }
}

This doesn't:

//> using scala 2.13
//> using dep org.scalameta::munit:1.1.0

import munit.Tag

class CustomFlakyTests extends munit.FunSuite {
  override def munitFlakyOK: Boolean = true

  private val CustomFlakyTag = new Tag("CustomFlaky")

  override def munitTestTransforms: List[TestTransform] =
    super.munitTestTransforms ++ List(
      new TestTransform(
        "Custom Flaky",
        { test =>
          if (test.tags.contains(CustomFlakyTag)) test.tag(munit.Flaky)
          else test
        }
      )
    )

  test("fail".tag(CustomFlakyTag)) {
    assert(false)
  }
}

Took me a good bit to figure out it's just the matter of order of transforms, and by the time I add the Flaky tag in mine, the tests have already been evaluated.
At least a warning would go a long way here, I think.
