#51302 closed defect (bug) (duplicate)

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

Reported by: rmens Owned by:

Severity: normal Version: 5.5.1
Component: Editor Keywords:
Focuses: rest-api Cc:


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"

Are the block marker comments being converted to \n?

Hi @joyously, after some more testing this does seem to be the case. Normal HTML-comments like <!-- this is a comment --> don't convert to \n but block markers are.

The difference in rendered content between the classic editor and block editor is the most problematic in this case. When there are some posts made with the classic editor and some with the block editor, the rendered output is no longer predictable.

  • Component changed from REST API to Editor
  • Focuses rest-api added

I'm moving this to the Editor component as it is responsible for rendering the raw content, the REST API only applies the the_content filter.
