FacebookDialog freezes my app again

[KAS1990]

When FacebookDialog is loading page my app interface is freezed. I found how to solve this bug. WebView should be constructed with argument WebViewExecutionMode::SeparateThread. I changed FacebookDialog.xaml, FacebookDialog.xaml.cpp, FacebookDialog.xaml.h, FacebookLoginButton.cpp, FacebookSession.cpp and FacebookSession.h. But i don't have permissions to merge my chenges to repository. I can send my changes to developers with such permissions, or anybody can suggest other solution. Please merge my changes to main branch.
I have created the same post 8 days ago, but i closed it by chance.
Please, help me to merge my changes, because problem is not solved
