[Bug] Typescript code in Vue template is not formatted

Prettier 2.8.4
Playground link

--parser vue

Input:

<script lang="ts"></script>

<template>
  <comp :foo="(a:string)=>1"/>
</template>

Output:

<script lang="ts"></script>

<template>
  <comp :foo="(a:string)=>1" />
</template>

Expected behavior:

<script lang="ts"></script>

<template>
  <comp :foo="(a: string) => 1" />
</template>

We only support typescript syntax when there are scripts with [lang="typescript"], but this still a bug. Updated code example to add a <script> block.

@wenfangdu
Would you try the playground of #14506 ?
I'm not familiar with Vue enough.

@seiyab Thanks, it seems to be working:
