Clojurians Log v2

I made a https://github.com/henrik42/clerk-playground for playing around with regular expressions but have problems with using https://github.com/nextjournal/clerk-slideshow with that. Without the slideshow everything is working fine. But after I add the slideshow-viewer (see slideshttps://github.com/henrik42/clerk-playground/compare/main...slides#diff-48b2b8db7cbfe7d3ca0ad6811b0a73dc0dfce4597beb8be6b1c707fe47f6afcbR7) I get

error in render-fn: Could not resolve symbol: user/reg-ex-input
[,,,]
error in render-fn: Could not resolve symbol: text

It must have to do with using the sync'ed vars in the render-fn but I can't figure out what's causing this. Any idea?
