### Describe the Bug

Updated to the latest Sunshine version (pre-release, `2026.608.233907-1`). After rebooting, the system icon for Sunshine is no longer visible. When right clicking the system tray icon, instead of a popover, a window in the middle of the screen appears. Here's a video reproducing the issue:

### Online logs

_No response_

Start by reproducing the issue after reboot on Linux/Wayland, using the system tray initialization shown in the log and comparing the behavior with #4907. Check why the tray icon is invisible and why right-click opens a centered window instead of a nearby popover. Done means the icon is visible and the popover appears beside it.
