linting from the command line with clj-kondo v2022.03.09 doesn't report any issues with this

I filed this under https://github.com/clojure-lsp/clojure-lsp/issues/888 just in case this is an actual bug somewhere and not just me messing up my system somehow

This is a recent bug in clj-kondo and has been fixed by reverting a commit on master. I hope @UKFSJSM38 can do a new release of LSP

Cc @U0508JT9N

I'll do a release today which will include this fix
