Steps to reproduce

Use 3.3+ syntax of defineEmits in combination with a Typescript enum

defineEmits<{
  [Some.Enum]: [],
}>()

Expected: Component should compile normally

Actual: [@vue/compiler-sfc] Unsupported computed key in type referenced by a macro

Any additional comments?

The older syntax of defineEmits works as expected
