[bug] Video player element's fullscreen not working in Tauri, working fine in browsers

[zespook]

Describe the bug

The video player element's native fullscreen function and F11 fullscreen within Tauri don't work, and the devtools console shows no error.

Trying it with the following tauri.conf.json does work, but without heavily implementing an additional fullscreen button, there doesn't seem to be a workaround:

...
  "app": {
    "windows": [
      {
        "maximized": true,
        "resizable": true,
        "fullscreen": true,
        "title": "zello",
        "width": 1600,
        "height": 900,
        "additionalBrowserArgs": "--force-color-profile=srgb"
      }
    ],
    "security": {
      "csp": null
    }
  },
...

On the other hand, it's working fine in web browser view. It was confirmed to be implemented in #13558, but I can't seem to get it working.

Tauri version: 2.5.1
Video player: Jellyfin
