I'm not familiar with Tangled, but by the time Disney got to Frozen, there was a trailer with Olaf & Sven that is basically a stand-alone scene not in the movie at all (intentionally). It's impressionistic more than trying to represent the film literally.

I am okay with that as a teaser, as long as it is billed as a short or it is made to be characters doing something.

Doing scenes within a movie and making it feel 100% as a trailer and then cutting it out is different.
