BUG: Toolbar/actionbar buttons do not work when there are multiple instances present (Even in your demo)

Version: 0.16.44

You can get the version by typing grapesjs.version into the console

Are you able to reproduce the bug from the demo?

• Yes
• No

What is the expected behavior? Every instance has their own toolbar working properly

Describe the bug detailed So previously i made another issue relating to instances #3354 , in this issue i conclude that it was my fault handling the instances improperly . Here i even stumble upon the bug even in the demo page https://grapesjs.com/docs/getting-started.html#theming. You can see that in every single instance no toolbar works, none of the options provided ( bold,strikethrough, link etc ), except the very last initiated instance. This also is what happening on my case ( toolbar only works on the last initiated instance ).

Are you able to attach screenshots, screencasts or a live demo? You can test this on the getting started demo page https://grapesjs.com/docs/getting-started.html#theming

• Yes (attach)
• No
