How to Detect the End of a Drag Operation After appWindow.startDragging(); on Windows?

[Horbin-Magician]

On macOS, I can use the mouseup event in a WebView, for example: @mouseup="handleMouseUp".
However, on Windows, when appWindow.startDragging(); is executed, the mouseout event will be triggered immediately, and after that, I am no longer able to capture the mouseup event. How can I detect when the user has finished dragging?

2 not-so-nice things come to mind:

1. listen to mousemove as well. Once you receive this event you can assume the user stopped dragging - this should be kept Windows only. Problem here is that this won't work if the user keeps their mouse completely still (fairly hard imo) on button release.
2. use something like the rdev crate on the rust side, it keeps reporting events here.

Thanks for your answer! I will try the above methods, but none of them seem elegant enough.
I'm curious if this is a feature of Webview under Windows? What can Tauri do in it?

I think this is another instance of the issue that the webview steals events and/or we cannot forward events into it. This has caused a bunch of problems so far and I believe this is one of them.

I don't think there's anything we can do to fix the mouse events but we may be able to provide a drag-stopped event you can listen to via tauri's own event API.

Thank you, that really helps!
