(Core :: DOM: Content Processes, defect)

Description

[Mike Conley (:mconley) (:⚙️)]

STR:

1) Visit http://test.jlongster.com/edit/new
2) Click on the green ↗ arrow in the top right

ER:

A popup window should open.

AR:

No activity. NS_ERROR_FAILURE from bundle.js in the error console for the page.

Here's the script that's running when clicking on that arrow:

 handlePopout: function() {
    go(function*() {
      let preview = window.open(
        '/preview',
        'preview',
        'width=800,height=600,resizable=1,scrollbars=1,dialog=1'
      );
      preview.focus();

      if(!this.previewWindow) {
        preview.addEventListener('load', () => {
          preview.postMessage({ post: this.state.post }, config.get('url'));
          preview.addEventListener('unload', () => {
            this.previewWindow = null;
          });
        }, false);
        this.previewWindow = preview;
      }
    }.bind(this));
  },
