why can't we just put <neon-animatable id>?

It technically works, however, I think it's less confusing to write id="", as
then we are explicitly giving it an empty string id, whereas the other way makes
it seem like it 'has a' id.

Alternatively I can change it back to id="main" for the default page in a
separate patch if the above seems confusing.

^ that

Sounds good I'll change it back to id="main" for all of them
