The ClojureScript implementation of {{ex-triage}} provides full path in {{:clojure.error/source}} when it should only provide the filename.
To repro, add a unit test to {{cljs.repl-test}}:
(deftest test-cljs-xxxx
(let [m {:phase :compilation
:via [{:data {:clojure.error/source "/home/me/project/src/foo/baz.cljs"}}]}]
(is (= "baz.cljs" (:clojure.error/source (cljs.repl/ex-triage m))))))
This fails with
FAIL in (test-cljs-xxxx) (core-advanced-test.js:1370:83)
expected: (= "baz.cljs" (:clojure.error/source (cljs.repl/ex-triage m)))
actual: (not (= "baz.cljs" "/home/me/project/src/foo/baz.cljs"))
