 * Hi there, I am new to WordPress and I am trying to add a custom <div> to a post.
   I am using a custom HTML block and trying to add the following (from code editor
   view):
 *     ```
       <!-- wp:paragraph -->
       <p>bleh</p>
       <!-- /wp:paragraph -->
   
       <!-- wp:html -->
       <div class="foo" foodata="mydata">why</div>
       <!-- /wp:html -->
       ```
   
 * and the rendered page ultimately has the following in it:
 *     ```
       <div class="entry-content">
           <p>bleh why</p>
       </div>
       ```
   
 * What is likely to be responsible for mangling my custom HTML and how do I make
   it stop?
 * FWIW, I am using the Twenty Twenty-One theme with no changes, and I installed
   a few plugins that I have since deactivated/uninstalled in the hopes that this
   would help me understand the problem (it didn’t). My server is running WordPress
   5.8.2.

 * I freshly installed WordPress (Twenty Twenty-One with no plugins) and could not
   recreate your issue. Here’s my post content from the front-end.
 *     ```
       <p>Welcome to WordPress. This is your first post. Edit or delete it, then start writing!</p>
   
       <div class="foo" foodata="mydata">why</div>
       ```
   
 * Here’s a similar situation where the problem was resolved by editing the post
   as a user with more capabilities.

 * This could be your solution if you’re running a multisite.

 * I appreciate the suggestion, but this does not appear to be my issue at first
   glance. I am editing as an Administrator and I do not think I have Multisite 
   enabled (though, to be honest, I do not know how to tell for certain). Moreover,
   the HTML I get is different from the “similar situation” link you provided. When
   I paste the content from that issue:
 *     ```
       <!-- wp:paragraph -->
       <p>before</p>
       <!-- /wp:paragraph -->
   
       <!-- wp:html -->
       <script>document.write('<div>hello world</div>');</script>
       <!-- /wp:html -->
   
       <!-- wp:paragraph -->
       <p>after</p>
       <!-- /wp:paragraph -->
       ```
   
 * I get even less:
 * `<p>before after</p>`

 * Oho, I think I’ve been tricked by the summary/excerpting feature of a page. My
   blog page has been getting a summary version of the post content, which is smashing
   paragraphs together etc. Knowing this, I managed to find the option in Excerpt
   Settings to turn that off. But thanks for the idea!
