webpack asset size vs chunk size

[eps1lon]

I noticed that upon moving files around that we get very strange differences in size reported: #14888.

The webpack stats are available for the base at https://circleci.com/gh/mui-org/material-ui/78237#artifacts/containers/0 and for the PR at https://circleci.com/gh/mui-org/material-ui/78307#artifacts/containers/0

What was weird is that the asset size for Modal changed by a whole kb while the size of the only chunk that was used stayed the same (parsed and gzipped). The modules didn't change which makes sense if the chunk didn't change.

My question is what the difference between asset and chunk size is? It seems like chunk size is more stable. We use the asset size since that was used by our previous solution (size-limit) and is closer to bundlephobia.com. Is this just some bundler deoptimization?
