I tried recording a video that showed that when AllowExternalDrop is set to false, the page cannot be dragged.
But after annotating AllowExternalDrop, the page returned to normal.
If you need me to provide the source code of the project, please let me know.

I believe this is by design. Setting AllowExternalDrop = false on the WinForms WebView2 will block any drag. So if by Vue you are referring to the javascript framework ie. content hosted in the WebView2, then setting AllowExternalDrop false will prevent drag.

Thank you for your reply. I must admit that this matter has been delayed on my part. Our front-end colleagues have redesigned this function.

I found an article that describes the role of this property: https://github.com/MicrosoftEdge/WebView2Feedback/blob/main/specs/APIReview_AllowExternalDrop.md

What I learned about its function from the document is: this property prohibits dragging external files into the interior, but does not prohibit dragging internal files to the exterior. It is on this basis that we believe there is a bug here.
