Render section with blocks use Section Rendering API.

Hi
I use the Section Rendering API to render the content of a section but the problem is that it cannot render the blocks that the section owns.

Example:

<div class="section-blocks">
	{%- for block in section.blocks -%}
		{%- case block.type -%}
			{%- when 'title' -%}
				<span>This is title</span>
			{%- when 'text' -%}
				<span>This is text</span>
		{%- endcase -%}
	{%- endfor -%}
</div>

{% schema %}
{
	"name": "Demo section",
	"tag": "section",
	"class": "demo-section",
	"settings": [],
	"blocks": [
		{
			"type": "title",
			"name": "the_title",
			"settings": []
		},
		{
			"type": "text",
			"name": "the_text",
			"settings": []
		}
	]
}
{% endschema %}

Normally, it will display the following content.

<div class="section-blocks">
	<span>This is title</span>
	<span>This is text</span>
</div>

But when using Section Rendering API, the content is only:

<div class="section-blocks"></div>

Section Rendering API does not support rendering blocks?
Or did I miss a document or tutorial?

Can someone explain it to me, thanks!

Start by reproducing the Section Rendering API scenario using the Liquid section and block example in the issue. Compare the normal render with the API response, then establish whether block rendering is supported and what behavior or documentation would define the issue as resolved.
