Applet keyboard shortcut does not work until manual intervention each session, is this a bug?

Hello! I’m running the latest Plasmashell version available on Arch (6.0.5).
I assigned a keyboard shortcut to an applet hidden in the system tray (in my case I assigned the “calculator” button to the qalculate applet). Every session, the shortcut does not work until I manually expand the system tray and then close it. I don’t need to expand the applet, just the system tray. Is this normal or a bug? has anyone else experienced this?
