Rendering a custom block with Twig Tweak more than once on a page results in the same content.

Problem/Motivation

I have a paragraph that calls a custom block plugin using the Twig Tweak patch from https://www.drupal.org/project/block_ajax/issues/3315618 ✨ Twig Tweak/Plugin Blocks support Fixed .

The block receives as an argument the paragraph ID. The build logic of the block makes decisions about what content to show.

This paragraph is used twice on the page. Both paragraphs end up with the same content.

Steps to reproduce

Using Twig Tweak, render the same block twice but different content is expected.

Here's my example code from the paragraph that is used twice on a page:

{{ drupal_block('pc_passthrough_block', { 'segment_set_paragraph_id': paragraph.id(), 'block_ajax': { 'is_ajax': 1, 'max_age': '0', 'show_spinner': 1, 'placeholder': 'loading....', 'ajax_defaults': { 'method': 'GET', 'timeout': '10000', 'others': { 'async': 'async', 'cache': 0 } } } }) }}

Easier to explain with the screencast:

Proposed resolution

Use a unique identifier for each instance a given block ID on a single page.

Remaining tasks

User interface changes

API changes

Data model changes
