1.) Have a page open in Live Mode (GoLive active)
2.) Open the Inline Editor with a class defined in multiple places (multiple results shown)
3.)Switch between the results

Result:

Developer Tool opens with errors -
A number of them stating "failed to load resource" pointing at localhost/json.
Following unhandled exception:

/C:/Users/pthiess/git/brackets-app/brackets/src/document/DocumentManager.js:394Uncaught Error: Document for this path already in _openDocuments!

There are two separate bugs here:

• "Document for this path already in _openDocuments!" is a bug with the rule list. I've spun that off as bug [CLOSED] Selecting a rule from a very long rule list may scroll the inline editor up or down alternately. #538 with new repro steps that don't require using live development at all.
• The "failed to load resource" localhost/json error is related to live development. Let's keep this bug open to track that one.

The "failed to load resources" error is an FOL. To establish a remote debugging connection, we try to get the JSON debugging information from port 9222, and handle any failures correctly in our code. These errors are expected and harmless. There is no way (that I could find) to suppress the error in the console.
