Directives inside modal scope don't correctly bind to the controller

When i create some directive in modal template definition and try send from modal controller some scope params in directive isolated scope, params in directive are undefined.

Demonstrating example:

Start with the jsfiddle demonstration linked in the issue and reproduce the undefined isolated-scope parameters from a directive inside a modal template. Trace how the modal controller scope is passed into the template and directive, then verify that the directive receives the expected values.
