Bug report

I have a library file that is used by both the client and the server that contains utilities for working with routes

One utility used only by the client uses react-router-dom

What is the current behavior?

When compiling the server build webpack is correctly eliminating the dead code that uses react-router-dom but it is not removing the react-router-dom import

If the current behavior is a bug, please provide the steps to reproduce.

I believe that this is a bug because the react-router-dom library is tagged with sideEffects: false in its package.json

I have created a minimal reproduction here: https://github.com/MJez29/webpack-harmony-side-effect-evaluation

In the logs I see

    | external "react-router-dom" 42 bytes [depth 2] [dependent] [built]
    |   [no exports used]
    |   harmony side effect evaluation react-router-dom ./src/lib.js 1:0-45
    |   [inactive] harmony import specifier react-router-dom ./src/lib.js 4:9-18

What is the expected behavior?

I expect react-router-dom to be completely removed from the build output because it is not used and it is labeled as not having any side effects
