Angular-Cli does not serve type:'HEAD' by default in development. This change introduced a small new bug for those that use it.

angular/angular-cli#5170
Current:

	// Test if a given url exists
	var file_exists = function(url) {
		return $.ajax({
			type: 'HEAD',
			url: url
		});
	};

Previously working in 2.7.0:

        // Test if a given url exists
        var file_exists = function(url) {
            return $.ajax({
                type: 'GET',
                url: url
            });
        };

It's not appropriate to use GET request just to check whether file exists. JS script code will stay with HEAD request. Try to modify the middleware to make it accept HEAD as discribed in webpack/webpack-dev-server#924 (comment)
