 Storing a multidimensional array, such as `$options['my-option'][$id] =
 "value"`, into the database using register_setting results in the "my-
 option" string getting double serialized. The option_value is stored as:

 `s:9:"'my-option'";a:1:{s:9:"option-id";s:5:"value";}`

 The my-option array is encased in both single and double quotes, so that
 `isset($options['option-id']` evaluates false, but `isset($options
 ["'option-id'"]` evaluates true.
