 The `widget_block_content` filter introduces invalid HTML when processing
 content from the Shortcode block. Specifically, when a shortcode returns a
 block-level element like a `<div>`, it is improperly wrapped in `<p>`
 tags, resulting in invalid markup.

 == Steps to Reproduce ==

 1. Create a simple shortcode in your theme or plugin:
    {{{#!php
    <?php
    add_shortcode( 'my_test_shortcode', function() {
        return '<div>something amazing...</div>';
    } );
    }}}

 2. Go to ''Appearance > Widgets'' in the WordPress admin area.

 3. Add a ''Shortcode block'' and use `[my_test_shortcode]` as its content.

 4. Save and view the output on the front-end. Notice that the `<div>`
 returned by the shortcode is wrapped in `<p>` tags, resulting in:
    {{{#!html
    <p><div>something amazing...</div></p>
    }}}

 == Expected Behavior ==

 The shortcode output should render the block-level `<div>` without
 additional wrapping `<p>` tags, maintaining valid HTML structure.

 == Proposed Solution ==

 Consider modifying the `widget_block_content` filter to handle shortcodes
 correctly and respect block-level elements, preventing improper wrapping
 by `wpautop`.
