ContentDialog Input not working for TextBox

[JanRajnoha]

Describe the bug
I tried create ContentDialog with input like TextBox or PasswordBox, but text input is not working. CheckBox (like in sample gallery) is okay. Shortcuts are okay and deleting chars (backspace or delete) is okay too. Content of ContentDialog is created as User Control (from WinUI 3) and testing it as Control in page is its behavior ok too. Is this behavior intentional?

Steps to reproduce the bug
ContentDialog with TextBox (or PasswordBox).

Actual behavior
Input from keyboard not working, Ctrl+V is okay, backspace is okay too.

Sounds like a bug with WinUI 3 controls, not a problem in Xaml Controls Gallery app. Moving repos.

I think there's still an issue in the XCG which needs to update the ContentDialog page to use XamlRoot. I wonder if this is a symptom of that.

[JanRajnoha]

Xaml root is not problem. I reported bug about it, but this is new. I assign into property button, which worked okay, everything was okay, but when I try text input, nothing.

Thanks for clarifying @JanRajnoha - in that case, I agree with @YuliKl that it sounds like this might be a platform issue.

@JanRajnoha do you know if this issue is unique to Winui3 or if its present in system xaml as well?
