Toolbox leaves ghost process after closing

I recently switched to Toolbox instead of installing each application manually via AUR. It is nice to have the plugins updated together with the IDE, however when I close the toolbox window, the `jetbrains-toolbox` process keeps running in the background and must be killed manually.

How can I debug this issue? It doesn't print anything to stdout or stderr when I close the window, and I cannot seem to find a log file for the Toolbox anywhere in the filesystem.
