undo/ctrl-z not working inside password field
Observation: When viewing login details in Seahorse and changing the text in the password field you can not undo your changes. This is not the worst situation, since Seahorse asks you to confirm the changes when closing the dialog. You won't accidentally delete or change your password that way, but it would be still useful to simply ctrl-z to undo an accidental change inside the open dialog.
tested in Seahorse: 3.30, Fedora 20
