Describe the bug

about build.target

The document shows

https://vite.dev/guide/build.html#browser-compatibility

Note that by default, Vite only handles syntax transforms and does not cover polyfills.

But the code comment shows except for dynamic import

A few days ago, we found dynamic-imports compatibility error, so I tried to found more info about the difference bwtween build.target and @vitejs/plugin-legacy, and then found there are some conflict description.

The comment was added since 4 years ago, maybe it is outdated?
