why the same chunk has difference hash in dynamic load

Bug report

What is the current behavior?

If the current behavior is a bug, please provide the steps to reproduce.
A and B module build as a chunk，and splitChunks set chunk is 'all'. But import by two entry, one is used async way, but another is used sync way. It will product one chunk with a hash, but async way has another hash without chunk.

just like this:
optimization: { namedModules: true, namedChunks: true, moduleIds: 'hashed', chunkIds: 'named', splitChunks: { cacheGroups: { 'react-data': { chunks: 'all', test: module => { return /[\\/](redux|react-redux|react-router-redux|redux-immutable|redux-thunk|immutable|immutablediff|immutablepatch)([\\/]|$)/.test(module.context); }, name: 'vendor-react-data', enforce: true, priority: 10, reuseExistingChunk: true } } } }

webpack version: "webpack": "4.16.0",

What is the expected behavior?

I think, it should be product one chunk and hash be consistent

Please use Dicussion for questions. I think it is bug in webpack, Can you update webpack version? 4.16 is very old
