Polymer2 does not support type extension. As such, elements that rely on it are updated. Instead of <select is="gr-select"><select> This will now be.. <gr-select> <select></select> </gr-select> This is similar to the implementation of iron-input, except that is more complex, as it is supporting both type extention and non-type extension. https://github.com/PolymerElements/iron-input/blob/master/iron-input.html Bug: Issue 6371 Change-Id: I31091ff24791a9dc073b3325c7b0daa1580b69ef
