I am running OSX 10.13.4 and latest Brave (updated this morning to 0.22.727) see below.
OS Release: 17.5.0
Update Channel: Release
OS Architecture: x64
OS Platform: macOS
Brave Sync: v1.4.2
I have the 1Password plugin installed.
If 1Password on the browser is not currently unlocked then I have to enter the 1Password master password in the extension (all good). I have 1Password running separately in the main OSX environment.
When I unlock 1Password in the extension, focus jumps back to 1Password (main window on OSX, outside Brave).
If I click back in to Brave and open 1Password again, it is already unlocked and opens up fine.
This is not a big deal but is annoying.
I guess first question is can this be reproduced, has anyone else seen this - if not then it is all my fault and I apologise.
