print trailing "\n" in multiline diff

assert.fixture fails even if the actual result is equal to the expected

is there any way to debug more, why the test fails, even the result is correct?

const formatT = suite("FORMAT")
formatT("correct format", () => {
  let input = `
  <div
    class="bg-red-500"
  >
  Test
  </div>
  `
  fixture(
    new Magician(new Processor(), input, "src/App.svelte").format().getCode(),
    `<div class="bg-red-500">Test</div>`
  )
})
formatT.run()

   FAIL  FORMAT  "correct format"
    Expected value to match fixture:  (fixture)

        Actual:
        L1 --<div·class="bg-red-500">Test</div>
        Expected:
        L1 ++<div·class="bg-red-500">Test</div>

Start with the failing case in tests/magician.ts and inspect the fixture assertion reported at node_modules/uvu/assert/index.js:77. Reproduce the multiline comparison and determine how the diff represents a trailing newline; done when the shown case clearly exposes that difference without obscuring the compared values.
