Hi folks, I can't get extension settings import to work on Brave. I tried following the steps on #8847 (comment) with source Chrome version 125.0.6422.142 and target Brave versions 1.67.115 Chromium: 126.0.6478.56 as well as 1.68.87 Chromium: 126.0.6478.56. I'm on macOS arm64.

In every test I did the extensions themselves were imported into Brave, but the settings did not carry over i.e. MetaMask did not give me the "Welcome back!" screen. I also tested uBO and did not see the custom filters get carried over.
Is this a regression?
