Created from a comment to bug #70393

Can't extract deeper after first element in array in version 0.3

How to repeat:
set @json = '[{"a":1,"b":2}, {"a":3,"b":4}]';
select CAST(json_extract(@json, 0, 'a') AS CHAR(10000));

returns: 1

set @json = '[{"a":1,"b":2}, {"a":3,"b":4}]';
select CAST(json_extract(@json, 1, 'a') AS CHAR(10000));

returns: NULL
expected: 3
