[XAML] VisualState does not support `Setters` and `Storyboard` at the same time

[baptiste-nv]

Current behavior

A VisualStates with both setters and storyboard only executes storyboard

Expected behavior

Both Setter and Storyboard should be executed

How to reproduce it (as minimally and precisely as possible)

• Create a control with VisualStates
• In the same visual state, add a setter (for example on TranslateTransform.X) and a storyboard (ex: double animation on TranslateTransform.Y)
• Notice that it works on UWP
• Notice that only storyboard is executed on iOS and Android

Environment

Nuget Package: Uno.UI 1.46.196-dev.2440

Affected platform(s):

• [X] iOS
• [X] Android
• [ ] WebAssembly
• [ ] WebAssembly renderers for Xamarin.Forms

Visual Studio:

• [X] 2019 (version: )
• [ ] for Mac (version: )

Relevant plugins:

Anything else we need to know?

Thanks for the report! This looks like it's a concurrency issue, it's most likely that the setters are applied first, then the story board, and it's most probably resetting the X value in this sample.

Does it work properly if the setters change another property that is not on the same sub-object ?
