Why does HTML entities are still encoded in Code Block?

Question

In the Code Block if I type in reversed character, they are encoded to HTML entities:

• Input:

• Output:

  <pre class="wp-block-code"><code>'&#91;] </code></pre>
  

Meanwhile, if I put them in the custom HTML block, the output characters aren't encode:

• Input:

• Output:

  <code>'[]</code>
  <code class="'[]"></code>
  <code><code class="'[]"></code></code>
  <pre class="wp-block-code"><code>'[]</code></pre>
  

I wonder why this should be the case? I enable troubleshooting mode and use the Twenty Twenty-One theme.

Answer 1

The Code Block is to display things just as you typed them, so it may encode to ensure no code actually executes.

The HTML block is the reverse - it is to execute code exactly as you typed it, so it doesn't encode.

This is intentional, so you can either show or execute code, depending on your needs. :)
