 When TinyMCE editor content has Gutenberg blocks in it, we can assume
 `<p>` paragraph tags are included too. In this scenario,
 `wp.editor.autop()` should not be applied to the content.

 However, even when `wp.editor.autop()` isn't applied, TinyMCE applies
 `<p>` paragraph tags to all root nodes (e.g. the content of Shortcode
 Blocks). We can mitigate this behavior by stripping `<p>` paragraph tags
 from Shortcode Blocks on the 'SaveContent' event.
