#45413: Paragraph Block: Issue with extensions and extraneous HTML

 WP Version: 5.0 RC, clean installation.

 Browser: Chrome Version 70.0.3538.77 (Official Build) (64-bit)

 Can be viewed: https://guten.dandulaney.com/2018/11/24/grammarly-testing/
 (view source on blocks 2-5)

 Issue:

 When using the Grammarly Chrome extension, as many do (and I assume other
 browser extensions that behave similarly, by temporarily inserting tags
 with a custom class to underline spelling errors), the paragraph blocks
 keep the extra formatting tags (see example above, view source, blocks
 2-5)

 Expectations:

 In the classic editor, there is no inclusion of these extraneous tags,
 just what is typed.

 Issue was also reported here, before I realized this should probably be on
