Re: getBoundingClientRect() to screen coodinate
Read this thread :

It has information for WebView4Delphi but it shows how to sent the element coordinates.
Use a JS extension to send the coordinates to Delphi :

The JSExtension demo uses a JavaScript extension with two methods : mouseover, sendresulttobrowser.
Copy that code and use "sendresulttobrowser" to send custom information from JavaScript to Delphi.
