The platform evalCond helper (used by render-to-html and render-to-dom) only handled clojure-style (test body test body ...) but components use scheme-style ((test body) (test body) ...). This caused "Not callable: true" errors when rendering cond with nested clause pairs, breaking the test dashboard and any page using scheme-style cond.
