Issue Overview

I'm rendering a block in PHP that display another post preview card so I simply use (in the render_callabck) :

$id = $attributes['postID'];

$post = get_post( $id );
$excerpt = get_the_excerpt( $id );

I get a Fatal error: Allowed memory size of... from PHP from get_the_excerpt()
It look like it's too much for WP to parse the gutenberg saved markup

The targeted post only has a few paragraphs and a read more tag.

The issue does not happen if I set manually an excerpt in the inspector.

This memory issue does not occur outside a block rendered in PHP

Steps to Reproduce

1. create a post with gutenberg
2. add a read more block but no excerpt on inspector
3. create a block rendering in PHP
4. on the render hook, try to get_post and get_the_excerpt

Expected Behavior

display everything

Current Behavior
