VS Codium for Wayland does not show the right titlebar icon

[SrS2225a]

Describe the bug
When opening VSCodium, the application does not set the correct icon for the window under Wayland sessions. Instead it uses the default Wayland icon.

Please confirm that this problem is VSCodium-specific

• This bug doesn't happen if I use Microsoft's Visual Studio Code. It only happens in VSCodium.

Please confirm that the issue/resolution isn't already documented

• I checked the Docs page and the Troubleshooting page and my issue is not mentioned there.

To Reproduce
Steps to reproduce the behavior:

1. Start a Wayland session (e.g., on GNOME or Sway).
2. Launch VSCodium.
3. Observe the titlebar/window icon displayed by Wayland.

Expected behavior
The application should display the correct VSCodium icon in the titlebar/window as expected.

Additional context
This issue does not occur under X11 sessions or when using Microsoft's Visual Studio Code. The issue seems specific to Wayland and VSCodium.

I encountered a similar issue in a pull request for SDR++ and was able to resolve it by explicitly setting the application ID for GLFW using the GLFW_WAYLAND_APP_ID window hint, which had to match the .desktop file. It might be worth investigating whether a similar approach can be applied to Electron (the framework used by VSCodium) to ensure that the correct application ID is set for Wayland sessions.
