Iframes on certain sites or sources don't allow fullscreen.

Tested on a fresh profile on firefox 109.0.1.
Video frames have no visible or clickable icon for going full screen and double-clicking on the video also doesn't send it to full screen. Selecting full screen on right click menu works as expected.
*The site in question is 9anime and sources are filemoon and streamtape. Gogoanime for example works as intended on dodostream.

The iframe property allow="fullscreen" is the cause of this behavior. I've tried to remove it but nothing has worked so far. I love web dev 🙃

@somnambulist247 You can use the PIP and fullscreen that, not elegant but it works.
