According to the phenomenon, I feel that issue is the same as #48457, and another related issue is maybe #41622.

I've written some tests to try to reproduce, but none of them have been able to reproduce, I checked the relevant code and didn't understand why this happened.

[crazycs520]

#54255 already fixed this issue.

@crazycs520 Can we close this issue?

[crazycs520]

This issue root cause is same with #53634
