[BUG] On mobile-webkit devices, page keeps resizing by itself and stops being responsive.

[Qibaoooo]

Context:

• Playwright Version: mcr.microsoft.com/playwright:v1.25.0-jammy
• Operating System: Linux
• Node.js version: v14.20.0
• Browser: mobile-WebKit
• Extra: issue only happens when run in container with mobile-webkit devices; any other combination of set-ups don't have this issue. So far only notice this issue when going to this page.

You can clone this repo and run the test in playwright container to reproduce error.

Experiencing the same issue, mobile-webkit works fine on my Mac but when I run it in a container (1.26.0-focal or jammy) screenshot comparisons stop working. I looked at the video playback and I see that the screen is constantly re-sizing which I think is causing the screenshot to fail because it is waiting for the page to be stable.

Also observing this error on v1.28.0 within the focal Docker image. The viewport is alternating very quickly between its intended width + height and the same dimensions divided by two.

Tried fiddling with the deviceScaleFactor using 1 as a value to disable high dpr emulation, it did not work.

+1 as described using mcr.microsoft.com/playwright:v1.27.0-focal

Still seeing this in 1.31.1, not using the docker container (but, running in Docker). Anyone have a workaround for CI scenarios?
