Pathauto forgets 'Automatic alias' checkbox setting - two problems

Steps to recreate:

1. Create new node (that has a Pathauto definition). In 'URL Path settings', 'Automatic alias' is checked by default, and the path is greyed out. Enter values for required fields and click 'Submit'.

2. Click 'Edit' to edit the node and scroll down to the 'URL Path Settings'. You can see the path that Pathauto has assigned to the node in the greyed-out box (e.g., 'frequently-asked-questions'). Uncheck 'Automatic alias' and enter a custom path, e.g. 'resources/faq'. Click Submit.

3. Click 'Edit' again to edit the node and scroll down to 'URL Path settings'. Problem #1 appears here: the 'Automatic alias' checkbox is CHECKED and the text box is greyed out again, when I would expect it to remember that I had inserted a custom/manual path (and to leave the checkbox unchecked and the text box editable).

4. Don't do anything to the path values, but still click 'Submit'.

5. Click 'Edit' again to edit the node and scroll down to 'URL Path settings'. Problem #2 appears here: the text in the greyed-out has now reverted back to the automatically generated path ('frequently-asked-question').
