### Describe the Bug

E029: Failsafe: The current sync run would delete 50% of your links on the server. Refusing to execute. Disable this failsafe in the profile settings if you want to proceed anyway. If you didn't cause this, you can use the manual sync buttons to override the local state on this device with the state on the server. If you believe this is a bug, please reach out to the developers with the debug log of this run. | Last synchronized: 3 minutes ago

### Expected Behavior

Should Sync without issues.

### To Reproduce

To Sync an already synced browser tabs

### Debug log provided

- [ ] I have provided a debug log file

Start by reproducing the already-synced browser-tab case with the Google Drive sync method and inspect the debug log for the E029 failsafe decision. Compare the local and server states, then verify that a normal sync no longer incorrectly predicts deletion of 50% of server links; the issue currently provides no debug log or named file/test.
