mdc-simple-menu firing "cancel" event when setting "open"?

What MDC-Web Version are you using?

`0.5.0

What browser(s) is this bug affecting?

Firefox 52.0, Chrome

What OS are you using?

Linux w/ kernel 4.9.11-1

What are the steps to reproduce the bug?

1. Click on the button that says “click me”.
2. Click on the button again. Notice in the console that the “cancel” event will continue to fire, but the menu will be hidden.

This isn’t exactly what’s happening to be but it’s related.

What is the expected behavior?

Ideally clicking the button again wouldn’t do anything, but the switch should toggle (and it does).

What is the actual behavior?

Clicking on the button again closes the menu, and then prevents it from being open again; each subsequent click will fire the “close” event.

Any other information you believe would be useful?

Here’s why this is a problem for me:

After toggling, clicking the “settings” button again does nothing, but the “cancel” event continues to fire.

I’m not entirely sure if I’m doing this right. I’ll try creating a component using the foundation class rather than using the menu-simple built in object and report back.

Sounds easy enough; I can give it a shot.

This is most likely obsolete since the Menu component has since been refactored. Feel free to comment if this is still reproducible with current MDCMenu.
