BUG: Flashing windows, no biometric auth with the latest 1Password & Wavebox & Sidekick

There are two issues with the latest version of 1Password and Wavebox which have been introduced with the latest version of the 1Password desktop app

Wavebox version: 10.115.15 -> 10.115.24
macOS: 13.4.1
1Password desktop app: 1Password for Mac 8.10.10 (81010014) (beta)
Safari: 16.5.2

1Password extension (Wavebox): 2.13.0
1Password extension (Safari) 2.13.0
Sidekick: 114.48.1.34403
1Password extension (Sidekick): 2.13.0

The first issue is that when the 1Password extension is installed in Wavebox or Sidekick and then in Safari, opening Safari causes macOS to flash between both browsers at speed. Removing the 1Password extension from any of the browsers stops the flashing. See the attached video:

The second issue is that biometric authentication has stopped working with version 8.10.10 beta of the 1Password desktop app. The extension always asks for the password (no error message).
