--- Comment #2 from Joseph Pecoraro <joepeck at webkit.org> ---
The way this worked before, is if an array was printed to the console it would auto-fetch one level deep and print that as an object. Currently, we drop the second level fetch and just go with the Preview, which for non-object data gets us less information.

Things we may want to try:

  - do a second level fetch for Arrays like we used to
    -> handles most of the cases above and is pretty straightforward

  - do a "n-deep" level fetch for Arrays/Objects that are simple
    - simple defined as: (arrays of length < 2, objects with less then 2 properties, non-cyclical)
    -> handles all cases above, but is more complex

  - proactively send out better previews for Arrays based on either of the above strategies
    - more complete snapshots instead of second level fetch where the objects could change
    - won't work with legacy backends since this would require InjectedScript changes
