[QWB] Table view is messed up if the result json is nested

Build : 7.1.0-2400

The table view on QWB gets messed up if the result json has nested and deep nested elements. Some controls like the < & > buttons, the context dropdown, and the links to toggle between table, json, chart etc are not shown.

Run a query like this to repro the issue : select * from system:completed_requests limit 2

Pls see the screen recording video attached for more details.
