core input grayed out during preview in Designer

Question

While using the designer i am following the Google I/O video which talks about creating a simple google map search app. In preview the core-input field does not take any input. It stays grayed out and non editable. Is this something anyone has tried and seen the same issue?

core-input does look like disabled 'cause it doesn't have any styling. According to the official link -

core-input is an unstyled single-line input field.

I believe what you were looking for is paper-input which is styled in favor of material design. Have a look at this demo, I created it followed by Rob's video a while ago.
