Drag&Drop within extension from one webview to the other not working with vscode > 1.90.0

Problem: In my extenstion, when I drag an object from one webview (tree view in attached Sample project) and drop it into another webview, vscode security asks me to press shift before the drop. Since the source is not outside the project, I ask myself, if this is really a wished behavior by vscode. I would understand the logic when my drag area is an external file system, but here everthing happens within the same extension. The behavior makes my extension less usable. Is there some kind of fix planned? Or is this as known issue?
I have attached a Sample extension to illustrate the behavior.

Does this issue occur when all extensions are disabled?: Yes
