#51302: Lots of newlines in REST API rendered content when using block editor

 In a post created with the block editor i have the following

 {{{
 <!-- wp:paragraph -->
 <p>This is paragraph 1</p>
 <!-- /wp:paragraph -->

 <!-- wp:paragraph -->
 <p>This is paragraph 2</p>
 <!-- /wp:paragraph -->
 }}}

 But the REST API renders the content as

 {{{
 "\n<p>This is paragraph 1</p>\n\n\n\n<p>This is paragraph 2</p>\n"
 }}}

 There seem to be 4 newlines between the paragraphs, while there should
 only be one. When I make the same post in the classic editor, it comes out
 like this. Which looks more correct.

 {{{
 "<p>This is paragraph 1</p>\n<p>This is paragraph 2</p>\n"
 }}}
