SourceMapDevToolPlugin not outputting full sourcemap during Hot Module Replacement

[baseten]

I'm submitting a bug report

Webpack version:
1.13.1

Please tell us about your environment:
OSX 10.11.3

Current behavior:
When using WebpackDevServer with HMR enabled and the SourceMapDevToolPlugin with the following options:

{
    test: /\.(js|jsx|css)($|\?)/i,
    filename: 'bundle.js.map',
    noSources: true,
    moduleFilenameTemplate: 'file://[absolute-resource-path]'
    fallbackModuleFilenameTemplate: 'file://[absolute-resource-path]?[hash]'
}

After changing a source file, the newly generated sourcemap only contains mappings for the file that changed and nothing else. I initially thought it may be related to this issue but even after doing a hard refresh the sourcemap remains the same. If using the devtool: 'sourcemap' option then everything works as expected.

Expected/desired behavior:
A new sourcemap should be generated for all source files.

remove the filename property.
