[Bug] Xamarin animation tasks do not complete on Android when Remove Animation setting is on

[janne-hmp]

Description

We have a problem in our game that the app hangs up with Samsung Android users when Settings -> Accessibility -> Visibility Enhancements -> Remove Animations option is on. I have not found a way to programmatically override this setting, while animator duration scale can be overriden, and Remove animations seems to override any other animator duration scale settings. Our app hangs to a call to Xamarin.Forms.VisualElement.FadeTo, with parameters (1, 250). The element is an FFImageLoading.Forms.CachedImage, but I doubt that this is relevant here. When Remove Animations is set to Off, the game works again.

Steps to Reproduce

1. Take an Samsung Android device and set Remove Animations option to Off under Settings -> Accessibility -> Visibility Enhancements.
2. Build GnollHack at https://github.com/hyvanmielenpelit/GnollHack/ for Android
3. Start debugging, and you will find out that the game hangs up in the first FadeTo call that never finishes.

Expected Behavior

The game does not hang up.

Actual Behavior

The game hangs up.

Workaround

User needs to set Remove Animations to Off, but this cannot be done programmatically at the moment.

I can add that build instructions for GnollHack Android are here: https://github.com/hyvanmielenpelit/GnollHack/wiki/Build-Instructions-for-Android-Version-on-Windows

There's a bug in the description. It should be:

Take a Samsung Android device and set Remove Animations option to On under Settings -> Accessibility -> Visibility Enhancements.

So the setting must be on to remove animations, not off.
