webpack-dev-server 2.8.1 triggers a bug in webpack-split-by-path

[hpatelx]

Running into this issue.

6% basic chunk optimization/home/project/node_modules/webpack-split-by-path/index.js:167
if (ignore[i].test(resourcePath)) {
^

TypeError: ignore[i].test is not a function


Webpack configuration:

const SplitByPathPlugin = require('webpack-split-by-path');

new SplitByPathPlugin([ {name: 'vendor', path: path.join(__dirname, 'node_modules')}, ], {ignore: [/style-loader/, /css-loader/, /less-loader/, /\.scss$/, /\.css$/]} ),

This issue is we have a polyfilled includes method on array. This breaks webpack
bundle generation since polyfill method is iterated in for loop.

for (var i in ignore) { if (ignore[i].test(resourcePath)) { return match; } }

This is caused by webpack-dev-server > 2.7.1.
Suggestion would be update for loop to iterate on own properties. I can submit pull req after some discussion to ensure I'm not the only one with this issue.
