Deleting field reverts to pathauto alias

When I use the "delete" link provided for a Field Collection field, it successfully deletes the field from my node. However, it also drops a custom node alias, if I have one set. In that case, the node alias is reverted to the pattern set in the Pathauto module.Here's the steps to reproduce:

1) Add a new content type, called Test Type.
2) Add a Field Collection field to this content type, called field_foo
3) Add a Text field to field_foo, called field_foo_bar
4) Create a node of type Test Type, with "My Title" entered for title and "abcde" entered for field_foo_bar
5) Give your new node a custom alias ("my-alias"), instead of using the default alias established by the Pathauto module (content/my-title).
6) Go to the view page for this node and hit the delete link for "abcde", then confirm the deletion.
7) Observe that the alias for this node is now "content/test" instead of "my-alias".

I am running Field Collection 7.x-1.x-dev and Pathauto 7.x-1.0-rc2
