[bug] [api.js] `appWindow.label` returns `null` instead of its label

Describe the bug

This (pseudo-ish) code is an example of the bug

// index.html
<script>
import { WebviewWindow } from "@tauri-apps/api/window";

const view = new WebviewWindow("uniqueLabel", {
  url: "/another-page.html"
});
</script>

// another-page.html
<script>
import { appWindow } from "@tauri-apps/api/window";

// this logs `null`, I expected it to be "uniqueLabel"
console.log(appWindow.label);
</script>
