Description

oxfmt --check hangs (does not finish within 10 seconds, likely indefinitely or in exponential time) when formatting a Vue file whose <script lang="ts" setup> contains a deeply nested chain of yup.object({...}) with arrow callbacks passed to .when(() => ...).

The same content placed in a plain .ts file is formatted instantly, so the issue is specific to the embedded formatter path used for <script> blocks in .vue files.

This is a regression introduced in 0.41.0 - 0.40.0 formats the file in ~0.3s.

Reproduction

<script lang="ts" setup>
const schema = computed(() =>
  yup.object({
    a: yup.object({
      b: yup.object({
        c: yup.object().when(() =>
          yup.object({
            d: yup.object().when(() =>
              yup.object({
                e: yup.object({ f: yup.object({ g: yup.string() }) }),
              }),
            ),
          }),
        ),
      }),
    }),
  }),
);
</script>

npm i
npm run reproduce

Actual result

oxfmt@0.40.0: OK  (0.3s)
oxfmt@0.41.0: HANG (10.4s)
oxfmt@0.49.0: HANG (10.6s)
