Shortcut Input field uses wrong keyboard layout and does not allow Cmd+# as a keyboard shortcut
I use 1Password in Firefox on Mac using the browser extension. The default keyboard shortcut for filling out a password form (Cmd+#) never worked in the browser. I tried to set it manually, but the input field in the extension settings stays blank when I try to input Cmd+#. When I enter a shotcut like Cmd+Z, it becomes obvious that the input field assumes a wrong keyboard layout (as it outputs Cmd+Y instead). Firefox itself seems to assume the correct keyboard layout (Cmd+Z works as expected, for example).
I don't know if these problems are connected. The problem I actually want to solve is using the same shortcut for the browser extension as for the OS level application (Cmd+#), as I had on my previous Mac without any manual configuration.
1Password Version: 7.9.9 (70909001)
Extension Version: 2.6.0
OS Version: MacOS 13.0
Browser:_ Firefox 109.0.1
