I came here to open a report because I have a 1.5MB XML file, and trying to format it appears to do nothing.

I believe what's happening is that the extension tries to do all the work in one big bite, takes longer than 5 seconds, and Code kills it and logs an error (visible under the Output tab, Log (Window) ).

Unfortunately I don't know if I can share the XML, which was produced by an internal system, but I suspect if you grab anything in the neighborhood of 2MB or bigger, you'll be able to reproduce this.
