Hello,
There was a recent change introduced to make DOM elements not expandable when inside an array. As a result, any node inside an array will not display its XML format, so HTML and the node's children won't be visible.
You can still do: $('#workgroups')[0] in your example to see the element's XML format. Alternatively, clicking a node in an expanded object switches you to the Elements panel. As PhistucK said, dirxml() will show XML format for array entries, but this was also changed in Canary. The motivation behind these changes is to avoid weird layouts in the console caused by nested expansion arrows.
If these changes have made your workflow worse, please let us know here
