[Android] Youtube fullscreen landscape view gets cut off at right and bottom (not because of chromium)

Description

Fullscreen landscape view does not show the bottom and right side of video. Everything is updated and does not happen in chrome, issue is only with Brave.

Note:

• Happens with brave shields disabled.
• There is no data saving settings turned on on my phone.
• There was another issue where people were saying it's because of chromium and waiting for them to fix. But not in my case, does not happen in chrome or other android webview based browsers.

Got a similar report from another user.

Pixel 9 Pro/Android15

When displaying YouTube videos in full screen landscape mode, it does not display in the original aspect ratio. This issue does not occur when viewing in portrait mode on YouTube app and other apps.

When displaying in full screen on the Brave, the aspect ratio is distorted, part of the video is not visible, and it is shifted to one side.

On Vivaldi, the aspect ratio is maintained properly except for being shifted to one side.

When displaying videos in full screen on the YouTube app, the aspect ratio is normal.

@iripu it is chromium related. I replicated it in Chrome as well. You have Zoom that is set to >100% in Settings->Accessibility or in a 3 dots->Zoom menu. I see that behaviour when I have it at 125% on both Brave and Chrome.
I created an upstream issue let's see what they respond https://issues.chromium.org/issues/421421331

@SergeyZhukovsky Yes. you are right. It was zoomed. But the webview browser was also zoomed the same 120% and it does not happen there. Anyway I am closing the issue here. Thanks.
