Description
## Bug Report
Please answer these questions before submitting your issue. Thanks!
### 1. Minimal reproduce step (Required)
After issue #64990 occurred, we restarted PD several times.
Subsequent wait-tiflash-ready steps in BR no longer behaved as expected.
### 2. What did you expect to see? (Required)
br should wait until TiFlash’s replication progress reaches 1.0 (fully replicated).
### 3. What did you see instead (Required)
br logs show TiFlash progress as 100%, but the actual state is not complete.
TiFlash still needs ~4 more hours to finish and reach progress = 1.0.
### 4. What is your TiDB version? (Required)
v7.5
