[Feature Request] Sort the JSON result

Some result is too long to read. Could add a button to sort result by the keys?

Start by locating the JSON result view and the controls around it; the issue does not name a file or test. Confirm how the result is currently rendered and determine where key sorting belongs. Done means a button lets users sort the displayed JSON result by keys and the behavior is covered by the relevant existing checks.
