Hi, when I pressed the Dialogue button, it showed this error in the console.

The issue seems not to be resolved as mentioned in #862

In my previous action, I deleted the Dialogue keywords.

I pulled from Articulate V1.0.0 Release. I ran on Window 10. Locally. Chrome.

Please help to fix the bug. Thanks.
