It's a large web app, sure, but gzip doesn't do 60x compression. 9-10x at best. But it's not a problem. It's for a small-ish group of people, and it's better to do the editing and some processing in the browser than on the server. The app uses relatively few components in that build at the same time, so it's not sluggish. There are also some "assets" in there. I don't like the practice, but my colleague does, so he occasionally puts things like images and fonts in there.
OTOH: it shows data. A normal size data set is 2000-3000x rows and 300-500 columns. If you output that as a simple table, the browsers gets super-slow. So another component has to be added. It adds up.
