BUG: optional multi-slot transclusion with jquery

I'm totally new to AngularJS, however, I believe I found an issue when jQuery is being included along with Angular, I could not reproduce the error when Angular is running without jQuery.
The situation is the following:

• jQuery is included.
• There's a directive with all the transclude slots marked as optional.
• There's a directive occurrence with no child slots defined.

You can check the following Plnkr: http://plnkr.co/edit/f9SN35IMPrmeyuPz0Pih?p=preview
The pane directive has no child nodes, all its transclude slots are optional, and you may notice the following error being raised in the console:

TypeError: Cannot read property 'replace' of undefined
    at directiveNormalize (angular.js:9033)
    at angular.js:8095
    at forEach (angular.js:354)
    at applyDirectivesToNode (angular.js:8094)
    at compileNodes (angular.js:7620)

If you remove the jQuery inclusion it all goes well.

it looks like this is a regression from 2c8d87e
#13171 should take care of this
