JSDoc removed from '.d.ts' when removeComments: true

[TheColorRed]

TypeScript Version: 2.0.3

.vscode/settings.json

{
    "typescript.tsdk": "./node_modules/typescript/lib"
}

./tsconfig.json

{
    "compilerOptions": {
        "target": "es6",
        "module": "system",
        "removeComments": true,
        "out": "./root/dist/javascript.js",
        "watch": true,
        "declaration": true
    }
}

Expected behavior:

When declaration: true and removeComments: true, I would expect comments to be removed from the javascript file(s), and leave the JSDoc in the .d.ts file(s).

Actual behavior:

All comments are removed from all files.

When declaration: true and removeComments: false comments don't get removed from the javascript file(s) but they do get removed from the .d.ts file(s) unless it is JSDoc.
