1. In the Git rebase operation, branch A falls behind branch B, and A will fast-forward to B. Click the Start (fast-forward) button. See Figure 1.
2. When rebasing again, it prompts: Rebase is not needed, A is identical to B. See Figure 2.
3. Check the Git log to confirm that its commit history is the same as that of remote branch B.
4. Force push local branch A to remote branch A. See Figure 3.
5. Create a new merge request; there are no commits between branch A and branch B. There are no commits yet. This matches the expectation. See Figure 4.
