Bug Report: `disablePictureInPicture` for html5 video elements are not supported

Eg:

```
    <video
    src="https://www.w3schools.com/tags/movie.mp4"
    disablePictureInPicture
    loop
    controls
    controlsList="nodownload"  
    ></video>
```

**What is the current behavior?**

Should remove the 3 dots (more button) on videos on Chrome:

**What is the expected behavior?**

Instead, the attribute is not taken into consideration so the more menu stays:
