metadata.toJSON does not respect typesAlias

Hi, I’m using the latest version of the polkadotjs. I found a problem that the typeAlias does not work when I use metadata.toJSON(). But the interesting thing is that if I use metadata.aslate.toJSON(), the type can be overwritten normally. I want to know whether this is a bug or a feature. The data I use is the https://github.com/polkadot-js/api/blob/master/packages/metadata/src/Metadata/v12/static.ts It works at 1.30.1 and V11

In the above, as a work-around for now, this should do the trick while solution is pending.

const metadata = new Metadata(registry, '0x......');

// HACK to populate registry
metadata.asLatest.toJSON();

const newMetadata = new Metadata(registry, metadata.toJSON())

The additional asLatest (while the output is not used), will enhance the registry so subsequent uses will have the added types.
