Hi @yukisakai1225, thanks for providing a detailed description of the issue. Using the steps you provided, I was able to reproduce the issue when using firebase-tools v11.23.1. I’ll relay this to the team so that they can take a look into it. That said, I'll be marking this as reproducible.

@yukisakai1225 Thanks for reporting the issue!

It looks like we accidentally broke this feature some time ago (#5083) - will make sure we ship a fix in the next release. Thank you!
