Upon enabling, existing tags with commas inside quotes split incorrectly

For example, if taxonomy/term/1 is "Emerson, Lake and Palmer", Active Tags's javascript will split it incorrectly when editing a node that already has that term assigned.

Steps to reproduce:

1) Fresh drupal install, and an autocomplete taxonomy (tags) vocabulary.
2) Create a single new node, and enter this in the autocomplete field:

"Emerson, Lake and Palmer", The Cure

3) Save node
4) Two terms are created: one for "Emerson, Lake and Palmer", and one for "The Cure".
5) Now, install, enable, configure Active Tags module
6) Edit above node. The active tags (incorrectly) shows 4 tags for the node:
"Emerson,
Lake
and Palmer"
The Cure

.. however I have not modified nor yet edited the node. There are still 2 terms in the vocabulary since the node has not been saved, and the term_node table (of course) shows there are two terms assigned to this node.

7) If you save the above node, changes are permanent; this has (incorrectly) created the new terms ""emerson", "lake", "and palmer"
