Compatibility issue with EditorsKit plugin

[poonam279]

Description

A user has reported that the block ‘Visualizer chart’ doesn't available in the block list if the EditorsKit plugin is enabled on the site. I am able to replicate it.

Also, when he creates a new page, get the following information in wp-debug bar:

TypeError: Super expression must either be null or a function, not undefinedhttp://localhost/demo-coachplatform/wp-content/plugins/visualizer/classes/Visualizer/Gutenberg/build/block.js?ver=3.10.7 line 7

And the console gives:

Uncaught TypeError: Super expression must either be null or a function, not undefined
