chunks broken in IE

I am trying to conditionally load a polyfill like this:

if (utils.needsHistoryPolyfill()) {
  require.ensure(['html5-history-api'], function(require) {
    require('html5-history-api');
    openApp();
  });
}
else {
  openApp();
}

If I do a hard-refresh, everything works. But on subsequent soft-refreshes (where the script jsonp response is loaded from cache in IE9), the chunk’s code is never executed.

googled a good article about IE loading issues here: http://www.guypo.com/ies-premature-execution-problem/ another solution is- set src attribute after adding element to the dom

looks like i’ve found the solution. Compare to previous 1.0 version scripts are coming with async = true flag. Tried to set it to false and it helps

I’ve branched from 2.1.0-beta.22 (latest versions doesnt work well properly with my config) and there is fix: https://github.com/Markosyan-AR/webpack/commit/8f0efcf7db0e22e9dfa9b300f50b0f1fc7d2d100

also faced my package.json to this branch "webpack": "https://github.com/Markosyan-AR/webpack/tarball/syncScriptsLoading"
