Not a regression as far as I can tell, and also affects regular JVM ClojureScript.
Attached patch with Mike's tests + tools.reader bump (which is where the fix is).
Blocked until some issues are sorted upstream in TRDR
I just release 1.0.5 which now requires cljs to resolve `Foo.` symbols to `their.ns/Foo.` in `resolve-symbol`. I realize this might be a bit annoying but it's the only way to support both clojure's behaviour of not including namespace segments and cljs' of requiring it
Attached CLJS-2261-2.patch which also bumps tools.reader to 1.0.5
