Aynchronous reactive commands on Avalonia.iOS never complete

[kyurkchyan]

Describe the bug

I have a straightforward scenario - a reactive command in the view model that invokes an awaitable async task. For the demo purposes, it's just Task.Delay(2000). The problem is that on iOS, when the command execution starts, it never completes. Please take a look at the demo project I've attached.

The command works as expected when launching the desktop version of the sample. In the demo project, I also have a Maui.iOS app that re-uses the same view model with the same set of bindings, and the reactive command works as expected there.

To Reproduce

1. Download the sample project
2. Launch the AvaloniaReactiveUIAsyncCommand.iOS on iOS Simulator
3. Press the "Load" button
4. Observe that the Load command is busy stays to value of "true" and the "Load" button is never reactivated.

Expected behavior

After the load command completes its execution, the load command should be reactivated and its IsExecuting property should be set back to true

Screenshots

If applicable, add screenshots to help explain your problem.
