Kibana Dashboard search blocks bracket characters in [] prefix

We are using ELK 9.4.3

We are seeing this error when searching our dashboard. I though using brackets was a naming convention from Kibana itself so why is it giving an error?

Thanks for reporting.

You can use "[WRA]" instead and that should work.

We worked around it by using WRA: My Dashboard. Is this an already know bug? Otherwise I will raise one.

I raised it internally, thanks to your report.
I'm not sure there's a public issue though about it.
