Using the classic editor, in WordPress 5.6.1, with concatenated scripts enabled, wp-tinymce.js includes the wp-view plugin. wp-tinymce does not wait for jQuery domready, and this causes wp-views to start initializing before shortcake views are registered. This results in existing shortcake shortcodes to not render in the editor on page load.
This can be fixed by moving the shortcode registration out of jQuery domready.

I have a fix for this coming in a few minutes.
