Could we close this PR?
Because I think at #4844, discussion will be lasted including QA's fix notice and so on.
Could you review the PR at #4844 again? Actually this and that PR are totally same.

@eido5 ,
QA team told me that they will fix CI problem by next week.
So, I think we don't need to close this PR and wait until they fix the problem.
After that, we can re-run CI again and expect to pass CI. So, please wait.
