Setting webpack.devtool = 'cheap-module-source-map' shows unreadable paths while debugging tests.

For example:

TypeError: undefined is not a function
  at <Jasmine>
  at MovementSystem.resolveCell (src/game-00/main.test.ts:215759:13)
  at ordered.filter.obj (src/game-00/main.test.ts:215718:42)
  ...

And without it (so probably 'cheap-eval-source-map')

TypeError: undefined is not a function
  at <Jasmine>
  at MovementSystem.resolveCell (webpack-internal:///./src/lib/game/ancient-maze/system/movement.system.ts:135:13)
  at ordered.filter.obj (webpack-internal:///./src/lib/game/ancient-maze/system/movement.system.ts:94:42)

This conflicts with https://reactjs.org/docs/cross-origin-errors.html more specifically this:

Some JavaScript bundlers may wrap the application code with eval statements in development. (For example Webpack will do this if devtool is set to any value containing the word “eval”.) This may cause errors to be treated as cross-origin.
