Hi Enpass team,
After being frustrated with Google Chat not working as I expected and blaming Brave for it, I stumbled upon this help thread: https://support.google.com/hangouts/thread/137003619/keyboard-loses-focus-in-google-chat-desktop-app
It seems that the autofilling feature of the extension breaks the "focus" on certain elements within these pages. Specifically, this has bitten me when trying to save calendar appointments using GMail (Google Workspace, using the sidebar), and when using Google Chat (focus is lost when exceeding single-line chat-box width). I've used the blacklist feature in the extension as a workaround (which solves my issue), but think this might be looking into.
Brave - Version 1.38.115 Chromium: 101.0.4951.64 (Official Build) (x86_64)
Enpass 6.8.0 - Mac App Store (Pro Lifetime)
Let me know if I can help by supplying anything additionally.
