IE 11 InvalidStateError during copyJSON

[tedfitzpatrick]

Hi, in IE 11 within the copyJSON function IE stops partway into the for ... in and reports InvalidStateError. Specifically when trying to access node[n] here:

if (opts.cull) {
                        if (node[n] || node[n] === 0 || node[n] === false) {
                            copy[n] = node[n];
                        }
                    } else {
                        copy[n] = node[n];
                    }

Hmm, can you pop in a breakpoint and tell me which node exactly is causing the breaking behavior?

[tedfitzpatrick]

I'll try to get to that ... I had to shift focus for a bit. From what I remember the node changed from unto run. You're probably interested in the type of node?

Type of the node and, if its an HTML node, what kind of tag it is. Plus anything else that you think is interesting about the node and would have caused the bug in question.
