md-subheader bug with ng-repeat-start

[jgoux]

Hello,
in order to display a hierarchical list, I use the ng-repeat-start directive.
Each time a md-subheader is added, I have an error in the console :

TypeError: el[0].querySelector is not a function

Here is an example : http://codepen.io/jgx/pen/mJOMZx

Fixed; should arrive in the 0.11 release.
