html2.WebView eats all shortcuts

Hi!
I have an application that previously used wx.html2.WebView with WEBVIEW_BACKEND_IE backend and worked fine. After switching to the WEBVIEW_BACKEND_EDGE backend, if focus is set on this control, WebView eats all shortcuts.
Is there a way to fix the hotkeys?
I found a description of a similar problem here - html - Python: Keyboard events not propagated from wx.html2.WebView widget to dialog - Stack Overflow

Windows 10, wxPython 4.2.1.
