Field data should not be altered in the entity when viewing a link field

Steps to reproduce:

$nid = // Some nid of a node that has a link with the title 'Foo & Bar' linked to 'http://example.com/'.
$node = node_load($nid);
debug($node->field_link);
node_view($node, 'full');
debug($node->field_link);

The first debug after node_load() will look like:

array (
  'und' => 
  array (
    0 => 
    array (
      'url' => 'http://example.com/',
      'title' => 'Foo & Bar',
      'attributes' => 
      array (
      ),
    ),
  ),
)

The second debug() after the call to node_view() results in:

array (
  'und' => 
  array (
    0 => 
    array (
      'url' => ''http://example.com/',
      'title' => 'Foo & Bar',
      'attributes' => 
      array (
      ),
      'display_url' => 'http://example.com/',
      'html' => true,
    ),
  ),
)

Notice the 'title' attribute has been escaped. Now if I'm trying to use this raw link data to output elsewhere, I'm screwed. The link module should *not* be altering field data on the node. If we were to call node_save() after this code, it would result in data loss as Foo & Bar would be saved as the 'title' value in the field.
