Not sure if this is the correct repo for this, however WinUI is also affected by this. When implementing an AutomationPeer, raising the AutomationPeer.RaiseEvent function does not always seem to work and calling AutomationPeer.RaisePropertyChangedEvent does not trigger narrator announcing changes either. A good example of this is the NumberBox control which calls AutomationPeer.RaisePropertyChangedEvent here, however Narrator does not announce changes. This function get's called when user presses enter on the NumberBox control for example.
I am running insider build 20236, is it possible that this is just an issue with my insider build?
Also @YuliKl a question regarding testing, what settings for narrator should be used for testing narrator compatibility and behavior (e.g. level of context or level of detail)?
