Sandboxed application can't communicate with browser extension

I have installed 1Password from the Ubuntu Software Center and installed the accompanying Chromium browser extension. When I launch 1Password, then go to Settings > Browser, I see the following text:

1Password detected that it is a sandboxed application. It won't be able to communicate with 1Password in the browser.

Is this expected and normal?

I understand that Snap packages are sandboxed; it's how I installed both 1Password and Chromium. And I get that 1Password for Linux is still somewhat new (grateful that it exists at all!) so I'm really just looking to find out what the intended experience is supposed to be.

Thanks!

1Password Version: 8.2.1
Extension Version: 2.1.3
OS Version: Ubuntu 20.04.2
