First block with InnerBlock is not refreshing on field change PRO 5.9.4

The fields in the admin sidebar don't receive the keyup event listener from acf-pro-blocks.min.js for the block added first in the sequence. Thus not triggering the expected refresh on the block.

To recreate:

1. Register new block type that supports jsx
2. Create field group for the new block type and add any field
3. Create the render template for the new block type and add the code below
4. Add the new block into a page twice
5. Change the value of the field in the block type for both blocks on the page. You will see that the first block does not trigger the refresh, whereas the second one works.

Add to function.php

<?php
add_action('acf/init', 'anything_acf_debug_block_init');
function anything_acf_debug_block_init()
{
    // check function exists
    if (function_exists('acf_register_block')) {
        // register blocks
        acf_register_block(array(
            'name'            => 'debug',
            'title'           => __('Debug block..'),
            'description'     => __('Description.'),
            'render_template' => 'template-parts/blocks/debug-block.php',
            'category'        => 'formatting',
            'mode'            => 'preview',
            'icon'            => 'admin-users',
            'keywords'        => array(),
            'supports'        => array(
                'align'  => false,
                'anchor' => true,
                'jsx'    => true
            )
        ));
    }
}

template-parts/blocks/debug-block.php

<?php var_dump(get_field('the_added_field')); ?>
<div>
  <InnerBlocks
        allowedBlocks="<?php echo esc_attr(wp_json_encode(['core/heading', 'core/paragraph'])); ?>"
        template="<?php echo esc_attr(wp_json_encode([['core/heading', ['placeholder' => 'Add header']], ['core/paragraph', ['placeholder' => 'Add paragraph']]])); ?>"
        templateLock="all"
    />
</div>

Expected behaviour

The block shall respond normally no matter in what sequence it is added.

Tested debugging steps (no avail)

• I have tried removing all other script assets on the site.
• Tried recreating new field group.

Versions

Wordpress: 5.6
ACF Pro: 5.9.4

edit; Adding tested debugging steps.

Reproduce the issue with WordPress 5.6 and ACF Pro 5.9.4 using the registration in functions.php and template-parts/blocks/debug-block.php. Inspect acf-pro-blocks.min.js and the keyup listener while changing fields in two InnerBlocks instances; done means both blocks refresh regardless of insertion order.
