What is the 1PasswordSLSNativeMessageHost process and why are the 70+ instances running?

I have a brand new, cleanly installed MacBookPro. I noticed a substantial performance decrease. While investigating the issue, I came across a process 1PasswordSLSNativeMessageHost. Activity monitor shows that there are dozens (79 when I counted them) of instances running. Each instance taking up approximately 6.5MB and around 10% CPU.
I can help but think that this is the smoking gun.

1Password Version: 7.9.3
Extension Version: 2.3.2
OS Version: macOS 12.3

    Just noticed that there’s other similar posts:

    Strange that the search didn’t reveal their existence…

    As this seems to be browser related, please note I’m using Wavebox, a chromium based browser. Already frustrating enough that 1Password refuses decent support for this browser, but this is simply ridiculous!
