I am working on a web app for iPadOS18.

As you can see in the picture, when the video is made full screen, the entire page is enlarged compared to iPadOS17 and earlier, and I am facing an issue where the full screen video cannot be viewed properly.

This was not the case prior to iPadOS17, and it is assumed that this iPadOS and Safari update has had some impact.

Video.js is used as the library for video playback.
The version of Video.js is 6.6.3.

I am aware that the Safari update changed the FullScreen related API, but the relevance of this issue is unknown.

Does anyone have a solution or know the cause of the problem?

Sorry for my poor English. I am Japanese.
