This is just about making object previews better for nodes. If you expand the preview and hover the object, it does highlight.

Still relevant.

I think this has been partially resolved by bug 194862 (and bug 209159).

Works well for me now. Feel free to reopen and retitle if you have a case when it doesn't.

IIRC this doesn't work yet for `Map`/`Set`/`WeakMap`/`WeakSet`. ``` new Set([document.body]) new WeakSet([document.body]) new Map([document.body, document.body]) new WeakMap([document.body, document.body]) ``` I thought there was a bug/FIXME for this, but maybe not.

I see. It still doesn't work for the previews of: ``` new Set([document.body]) new WeakSet([document.body]) new Map([[document.body, document.body]]) new WeakMap([[document.body, document.body]]) ```

Filed bug 315583 to track the underlying issue where node highlights can diverge from preview text after the object is mutated.
