Does registerButton only need to be called once (vs. a call for each instance of the toolbar)?
Instead of keeping the parents, should we walk up from env.element to find the pre?

The registerButton needs to be called once otherwise it register all the buttons for each of the codes.
For parents I did try to walk up but it didn't work.

Is Array.from necessary? I think toolbars.forEach would exist.

No I just changed the existed code that used it, I'll update it

do we need to setup this event handler for every codepen? Could event delegation be used to help peformance?

@cherifGsoul is this good to go? |
I think so, @chasenlehara do you want to take a look before merging it? |

I think you can just return demoWrapper instead of assigning it to a variable.

This event listener only gets added once, right? It doesn’t get added for each button?
[I see the event delegation, which is nice, but I want to double check that the listener isn’t added multiple times. If it is, this logic should be moved outside the registerButton call.]
For canjs/bit-docs-html-canjs#561
This adds
Runbutton to run code in CodePen, the logic behind the changes:I upgraded Zombie in order to use modern browser functions.
