Clicking system tray applet (AppIndicator) opens Seahorse (Passwords and Keys) in Gnome

I believe I've found out why the issue occurs. It appears that "Tray Icons: Reloaded" searches all applications for the Window Manager Class, which is reported as "Password" for 1password (see https://github.com/MartinPL/Tray-Icons-Reloaded/blob/5891310a217cd80416c057d87d4a25e4787afb92/AppManager.js#L92 in the extension source-code). The extension uses the function "lookup_app" https://github.com/MartinPL/Tray-Icons-Reloaded/blob/5891310a217cd80416c057d87d4a25e4787afb92/AppManager.js#L96, which returns a list containing all applications that match the term "Password". This includes Seahorse and even Gnome User Accounts Panel where users change their passwords. The extension takes the first match as correct, as "lookup_app" orders by some score, and thus Seahorse is launched. I believe this is an issue with the extension and not 1password.
