[Problem/Bug]: WPF and WebView2 - Setting Focusable property false does not prevent focusing on WebView component

[adorian-alt]

What happened?

We need to allow users interaction with WebView component while having focus on another element.
Setting WebView2's Focusable property to false does not seem to work, clicking on WebView componet always focuses on it (GotFocus is triggered when clicking on WebView).

How can it be achieved?
