## Steps to reproduce

1. Open https://nocebo.jp/html5_video_fullscreen/
2. Scroll to the embed Codepen iframe.
3. Click Big Buck Bunny's thumbnail.


## Actual Result

Safari does not expand "Big Buck Bunny" video to fullscreen.
Please see the screenshot I attached to this.

The embedded is https://codepen.io/nocebojp/pen/JzYYgx

But this bug is not reproducible if I open it without embedder.

I think this has been fixed in:

- Safari TP Release 163 (Safari 16.4, WebKit 18615.1.18.100.1)
- Safari TP Release 164 (Safari 16.4, WebKit 18616.1.2)

Thank you!
