Incorrect work area calculation web (WASM) on android

[AlexeyTliss]

Describe the bug

When opening web application (Avalonia.Browser) from android-based mobile device on chromium browsers (Chrome, Edge, Opera) avalonia application doesn't calculate work area correctly, seemingly not taking into account browser's tool area (adress textbox, tabs) into account, and not substracting browser's tool area rect from work area rect. As a result, some of content is out of window bounds.

To Reproduce

Host browser version of application on any machine by any means (direct, nginx, apache)
Go to application web adress from any mobile android device (preferebly not emulator)
See error: page size is calculated incorrectly and there is no footer (see screenshots)

Expected behavior

All of page content is fit into a browser window on mobile android device

Screenshots

1: Desktop browser: no bug, footer is clearly visible
2: Android tablet, horizontal mode: footer is missing
3: Android tablet, vertical mode: footer is missing
