PyQt6 WebEngineView - Windows 10 virtual keyboard issue

Question

In pyqt6 QWebEngineView I load an url (e.g: w3schools modal) on Windows 10 (input: touch screen, without keyboard)

My problem is that, when the user open a Modal (like in the link), and if it has an input field the Windows 10 virtual keyboard shows properly. When the user touch on the Close icon (on the virtual keyboard), the keyboard disappear properly. But when the user touch the screen again the virtual keyboard shows again, but there is no input field.

I have tried the catch the events like focus, toucing but it doesnt help.
