DataGrid binding in macOS not working for asynchronously fetched data

[AmitEMV]

Current behavior

DataGrid's ItemSource is bound to a List from the ViewModel. This List is populated during load asynchronously and in this scenario, it hangs\crashes on macOS. The DataGrid is in a DataTemplate which is used in a ContentPresenter finally.

Expected behavior

List will bind successfully and the app will display the bound data.

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

Simple repo to reproduce the issue. Running the app reproduces the issue as there is nothing else in the code - delay is simulated for the asynchronous action and data is bound after that.

Works on UWP/WinUI

It works in UWP, Android and Linux (SKia.Gtk) as well. Here is another repo targeting these platforms for the same behaviour.

I removed other project heads before checking it into Git, so they're absent in the macOS repo.

@jeromelaban Is there any workaround that you would recommend that I can use for now?

This is no longer relevant as we have a new macOS backend 🚀
