Let's put some multi-line query into the query editor tab.
F5 executes it and shows result in a Result tab below.
Now let's select just some blanks or tabs (no real characters) in the query editor above and press F5 again.
Result tab now disappears and "Messages" tab becomes active but it still shows result from the last successful query (see attached file).
The message "No query(s) were executed...." appears only after clicking on other tab (eg. Objects) and then again on "Messages".
