Can't edit stored passwords in a sandboxed Chrome or Brave browser

[NewKidOnTheBlock]

Describe what you noticed and did

1. Install Chrome Portable (https://portableapps.com/apps/internet/google_chrome_portable) or Brave (https://github.com/brave/brave-browser/releases/download/v1.66.118/BraveBrowserStandaloneSetup.exe) into a Sandbox
2. Store the password for a website
3. Go to Settings -> Password Manager
4. Try to edit or delete a stored password by clicking on an entry in the list -> You are notified that CredentialUIBroker.exe has crashed. Chrome still keeps running, but stored passwords cannot be edited or deleted.

Try disabling the FakeAdminRigths setting for CredentialUIBroker.exe.

FakeAdminRights=CredentialUIBroker.exe,n
