Expected Behavior

For the entries in "entrypoints" in the asset manifest to also be keys in "origins"

Current Behavior

I have a situation where the above isn't happening.

I think what is happening is that:

• I use react-loadable for a small component.
• I think webpack is seeing enough overlap between my entrypoint and the small component to combine them into one chunk.
• Then when getChunkOrigin runs, it finds the import statement for my small component (which is also the entrypoint chunk) and adds an entry into "origins" under /Components/SmallComponent
• origins.size is not 0 and therefore names[0] (the name of the entrypoint) is never added as an origin key.
• This then causes the entrypoint bundles not to be loaded

Possible Solution

Potentially adding something like this to the end of getChunkOrigin:

    if (this.entrypoints.has(names[0])) {
      origins.add(names[0]);
    }

I'm working with a very rudimentary understanding of how things work so I don't know if this is the right approach and, if so, whether we also need to check the other entries in names or against the id too.
