 ; This functionality provides a workaround to issue #22 (https://github.com/binaryage/cljs-devtools/issues/22).
 ; The idea is to track hierarchy depth for json-ml(s) we are generating.
-; If we are about to cross the depth limit hardcoded in WebKit we instead
-; render simple expandable placeholders which resume full rendering in their bodies (when expanded by user).
