Cannot run WebGPU Deno Desktop apps, even through Steam

Version: Deno 2.9.2

System:

• 64-bit AMD Ryzen 7 9800X3D
• 64 GB RAM
• AMD Radeon RX 7900 XTX
• NixOS unstable (26.11, revision 1d4e0f865d68258aada31e68e6d79c8c463f3b34)
• DE: Hyprland 0.55.4
• Using nix-ld to run unpatched Linux binaries

Steps to Reproduce:

• Create the files deno.json and main.ts in a new directory deno-desktop-sandbox exactly as outlined in https://docs.deno.com/runtime/desktop/webgpu/
• $ deno desktop main.ts
• cd deno-desktop-sandbox
• ./deno-desktop-sandbox

Expected results:

• A new window appears, cleared to teal

Actual results:

./deno-desktop-sandbox: error while loading shared libraries: libxdo.so.3: cannot open shared object file: No such file or directory

I have not been able to locate a NixOS package that provides libxdo.so.3 - the xdo and xdotool packages do not contain it.

EDIT: The same issue also happens when attempting to run the resulting binary through Steam (it crashes immediately without showing a window). So this is not a NixOS exclusive problem.
