Unable to resolve source-map issue in closure-loader

[vmonisha69]

ERROR in ./content/closure-polyfill.js
Module build failed: TypeError: aSourceMapConsumer.eachMapping is not a function

It is hard to say without a stacktrace. Perhaps the wrong version of source-map is being loaded?

Closing since we're lacking a clear reproduction / test case for this error.
