@fujitatomoya Thanks for opening this PR. Don't worry about the linter, it is failing in lines you didn't change.

It would be nice if you could add a regression test for this.

@MiguelCompany it is hard for me to find the appropriate place where to add the regression test... if you can point the existed similar test cases aligned with this PR, that would be really appreciated.
