1password often ends up with multiple instances running (each with its own trayicon)

I regularly launch the 1password standalone app (using rofi as my launcher). and I also use the Chrome extension too.

Over time I often notice that there are several instances of 1Password running, each one with its own trayicon.
Usually 2 when I notice, but I've also seen 3 on one occasion
These are independant processes, since I can quit one via the tray and it doesn't affect the others, and ps confirms this too.
I have 1Pass settings to 'minimize to tray' instead of quitting.

I haven't yet figured out what causes more than one to appear.
Anyone else seeing this problem? I don't know enough about linux yet to say it's a 1Password problem, or some config issue with my environment/desktop etc.

Can you shed any light on how exactly 1Password decides if there is already an existing instance?
Maybe that will help troubleshoot it

Thanks
