WebView2 clumsy drag and drop behavior within webview2 itself

[HO-COOH]

Describe the bug

Webview2 is behaving wired when dragging text/image within the webview2 itself. It is clearly having issues compared to Edge, for example. And this is bringing huge problem for our frontend team to maintain feature compatibility.
I also tried and this is NOT solved with 1.5 experiment release.
Related issue: #2715

Steps to reproduce the bug

1. Open WinUI3 gallery
2. Go to webview2 page
3. Right click, open the console
4. Go to google.com by using this (just for comparison with Edge)

window.location.href = "https://www.google.com"

5. Try dragging text and images

You CANT drag the google logo into the text box using webview2, but you can with Edge.
