Changing focus to other TextBox by using Focus() method does not work until clicking to control by actual mouse

Hi. I used CefGlue WebView on my Avalonia UI project. And trying to implement Ctrl+F (search feature)

My UI has WebView control and TextBox (for search) control. And I handle keypress event by using KeyboardHandler.

When Ctrl+F is invoked, I change focus from WebView to TextBox by using TextBox.Focus() method. But TextBox does not receive any key event (but its visual is changed) until clicking TextBox by mouse.

It seems that TextBox.Focus() does not change focus from WebView, and WebView has still focus (textbox on webpage still has cursor and receive keyboard input).
