Please stop posting `null` issue comments here. There is an issue #142

The issue has been addressed within #146, #140, #129 and #134. Most of the unmapped bytes were actually sourceMappingURL comments or 'null' (generated) source bytes. Closing the issue. Feel free...

I think this issue should be fixed on `dart-sass` side. `source-map-explorer` can't say what unmapped content refers to. ``` unmappedBytes = totalBytes - mappedBytes - sourceMapCommentBytes - eolBytes; ```

Could you provide an example what do you mean by contributors to JSON file size? Is JSON file somewhat bundled? I thought if a JSON is referenced within Webpack project...

I think it should be a separate utility. I can't imagine how we can leverage most of the existing `source-map-explorer` code. Perhaps we can extract visualization logic into separate package

I think it's because of fade in/out effect. Here a version with disabled fade [sme-result-2020419-3004-15b2otx.wtd1.html.zip](https://github.com/danvk/source-map-explorer/files/4652631/sme-result-2020419-3004-15b2otx.wtd1.html.zip)
