Warp taskbar icon not working properly on Linux

Zero Trust WARP
1

My system:

OS: EndeavourOS Linux x86_64 
Kernel: 6.3.6-zen1-1-zen 
Shell: zsh 5.9 
DE: Plasma 5.27.5 
GPU: NVIDIA GeForce GTX 1070 
Memory: 15911MiB

I’ve installed cloudflare-warp from AUR, and after registering service properly, I enabled its taskbar service with

$ systemctl --user enable --now warp-taskbar

Now a new icon (Zero Trust Client) is shown in my system tray, when I start service with

$ sudo systemctl start warp-svc

That icon reflects the current status of the service (red color), but after stopping service with

$ sudo systemctl stop warp-svc

that icon stays permanently in white color, not changing color even when I start service again. What’s going on?
