Description

Mapping over a selection with a function that returns arrays will flatten all returned values into a 1d array, instead of returning a 2d array as expected.

To reproduce:

$('<p/>').map(function() { return [1,2]; }).get(); // [1,2]
$('<p/><p/>').map(function() { return [1,2]; }).get(); // [1,2,1,2]

instead of returning a 2d array as expected.

Was that expected after reading the docs?

The function can return an individual data item or an array of data items to be inserted into the resulting set. If an array is returned, the elements inside the array are inserted into the set. -- http://api.jquery.com/map/
