When browse a empty table by open a new tab, page content is empty, without any message(such as "MySQL returned an empty result set (i.e. zero rows). (Query took 0.0003 sec)")
For example:
sql.php?db=performance_schema&table=events_waits_history&server=1&target=&token=9e11c7f660c8c1a2f31fa82ef82751d4#PMAURL-0:sql.php?db=performance_schema&table=events_waits_history&server=1&target=
This is due to the function "PMA_sendQueryResponseForNoResultsReturned()" in "sql.lib.php" sends the response only if the request is AJAX. I changed it and sent a pull request.
