1. Run a select query to show a few results. (e.g. "select * from table where name-'John'")
2a. Edit the fields that you selected on (using inline editor), so that running the same query again would return no results. (e.g. change 'John' to 'Dave')
2b. OR, delete those same rows in another tab.
3. Press the "Show" button at the top of the page to reshow.
Instead of showing the usual page saying there were no results, the entire page goes blank apart from the tabs at the top.
