Dropping files doesn't work on Wayland

[breard-r]

Problem

When using a Wayland-based WM/DE (Hyprland, GNOME 3,…), dropping files (ondrop) always return an empty list of files. The same machine, when using an X-based desktop environment (Cinnamon,…), doesn't have this issue.

Steps To Reproduce

Steps to reproduce the behavior:

• Use any Wayland-based WM or DE
• cargo r --example file_upload
• Click on Choose Files and select a file: it works
• Click on Clear Files
• Drag and drop the same file on the drop area: it does not work

Expected behavior

Dragging and dropping a file in the drop area should have the same effect as selecting it using the Choose Files button.

Environment:

• Dioxus version: v0.5.6
• Rust version: stable (v1.82.0)
• OS info: ArchLinux with Hyprland // Ubuntu 24.04.1 with GNOME 3
• App platform: desktop

Notes

I noticed the idea to switch from tao to winit #2706

However, winit seems to have the same issue: rust-windowing/winit#720 rust-windowing/winit#1881
