Details

From github: https://github.com/mozilla-mobile/fenix/issues/20405.

Steps to reproduce

  1. Open this page on your FF mobile: 
    <!DOCTYPE html>
<html>
<body style="height: 100vh; font-size: 8vw">
  <p id="debug"></p>
  <script>
    document.body.addEventListener('click', ()=> {
      debug.style.background = '#FF0'
      document.body.requestFullscreen()
    })
    setInterval(()=> {
      debug.innerText = `
      ${screen.orientation.type}
      ${screen.orientation.angle}deg
      `
    }, 200)
  </script>
</body>
</html>
  2. Touch the screen to call requestFullscreen().
  3. Rotate from portrait to landscape-primary or secondary.
  4. Flip you phone, like a coin, to the oposite landscape.
  5. See the screen to flip, but no change on the screen.orientation data.

Expected behaviour

The screen.orientation data should represent actual mobile position.

Actual behaviour

It do not updates screen.orientation data if you do not turn to portrait between the rotation from one landscape to another.

Testcase from the reporter

I can reproduce this on my Galaxy Note 8 and it seems it doesn't need to be fullscreen. But I don't have a good way to debug this as I have no Android dev setup and this is not supported at all on Windows. I wonder some non-Windows people can, maybe Edgar?
