WordPress AJAX Excerpt Length Issue 6.3

[wpcodeus]

One of our plugins are utilizing the WordPress AJAX do_action( "wp_ajax_{$action}" ); function to create an archive and shortcode that loads a custom post type with AJAX and Infinity scroll.

With WordPress 6.3 we experienced a weird conflict with the built in the_excerpt() function where any post type that was loaded with AJAX, the defined excerpt length was ignored. Excerpt length works everywhere else besides with the use of AJAX.

Is this a known issue? In the meantime, we have added some logic to detect if AJAX is being used and defined the excerpt length using wp_trim_words();

Below is an example of our temporary fix:

<?php

// Check if it's an AJAX request
        if (defined('DOING_AJAX') && DOING_AJAX) {
            $excerpt = wp_trim_words(get_the_content(), (int) $asp_expect_length, '...');

            // Check if the read more link should be appended
            if (empty($asp_disable_read_more) && $post->post_type == 'sermons') {
                $excerpt .= sprintf(' <a class="asp-read-more" href="%1$s" target="%2$s">%3$s</a>',
                    get_permalink(get_the_ID()), $asp_target_control, __('read more', 'advanced-sermons'));
            }

        } else {
            $excerpt = get_the_excerpt();
        }

I thought we would report our issue incase this needs to be investigated further.

If you would like access to our github to review the code for troubleshooting please let me know.
