Additional context

Broken since 15.0.3-canary.7, because on 15.0.3-canary.6 it works

Start with the reproduction repository at https://github.com/gavrilikhin-d/repro and run npm install, npm run build, and npm run start. Use the browser Network tab while loading the dynamic component, then compare behavior between 15.0.3-canary.6, 15.0.3-canary.7, and 15.0.3. Done means webpackPrefetch: true causes the expected prefetch request in production.
