Feature Request: Automattic EventTarget detection

[cawa-93]

I have simple code in template:

      <a
        href="https://github.com/cawa-93/anime-library/issues/new/choose"
        @click.prevent="openURL($event.target.href)"
      >🐞 Bug</a>

And I got TS error:

error TS2531: Object is possibly 'null'.
     @click.prevent="openURL($event.target.href)"
                             ~~~~~~~~~~~~~

error TS2339: Property 'href' does not exist on type 'EventTarget'.
     @click.prevent="openURL($event.target.href)"
                                           ~~~~

It would be fantastic if the TS determined that

1. EventTarget actually is HTMLAnchorElement
2. It is guaranteed exist

I use vue-tsc with PhpSthorm if this have matter

Event types is upstream problem, it's define in vue-next: https://github.com/vuejs/vue-next/blob/ecd97ee6e465ec5c841d58d96833fece4e899785/packages/runtime-dom/types/jsx.d.ts#L1183-L1297

Please wait for TS support in template: vuejs/core#1359
You can do this after it's supported openURL(($event.target as HTMLAnchorElement).href).
