[MVUX] Commands are not sharing the same SourceContext

[dr1rrb]

Current behavior

When creating a command, the context used is not the same as the context used by a FeedView on the same page. This drives teh commands to not have the value as what is displayed in the view.

Expected behavior

They share the same SourceContext so they will share the same subscription on the Feed, so they will have the same value.

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

public Feed<int> MyFeed => Feed.Async(async ct => new Random(DateTime.Now.MilliSeconds).Next());

public void DoSomething(int myFeed, CancellationToken ct)
{
}

<StackPanel>
    <FeedView Source="{Binding MyFeed}" />
    <Button Command="{Binding DoSomething}" />
</StackPanel>

Notice that the value got in the DoSomething is not the same as the one got in the UI.
