"sortable" attribute value is removed

[hbaccara]

I am using an attribute named sortable in my AngularJS templates the following way:
sortable="name", sortable="age", ...
The problem is that when I build the application, grunt-angular-templates removes the sortable attribute value. So, sortable="name" becomes sortable.
I have been able to get around this issue by using data-sortable instead but it would be nice if it is fixed so that other people don't waste their time in the future trying to understand why their Grunt built application is not working correctly.

I also wasted time on this. Thanks @hbaccara for the info.
