"noEmit": true with configFileName doesn't work

I use storybook, but want to provide different tsconfig.json to storybook.

So- I add this options to <ProjectRoot>/.storybook/webpack.config.js

        storybookBaseConfig.module.rules.push({
		test: /\.tsx?$/,
		loader: 'awesome-typescript-loader',
		include: resolvePath('src'),
		exclude: /node_modules/,
		options: {
			configFileName: '.storybook/tsconfig.json',
		}
	})

Even this new <ProjectRoot>/.storybook/tsconfig.json has "noEmit": true, when webpack's hot module replacement rebuild the codes, It emits the js files.

When I add "noEmit": true on the original tsconfig.json which is on <ProjectRoot>/tsconfig.json now webpack does not emit js files.

shortly: at-loader doesn't seems to use provided configFile's noEmit options. it loads and use the options from <ProjectRoot>/tsconfig.json
