Shortcode execution in post excerpt

Hi,

It seems that when we call a post preview with Timber…

{{ post.preview.read_more('') }}

… shortcodes are parsed, executed and stripped. In WordPress native get_the_excerpt function, shortcodes are stripped with strip_shortcode function (https://codex.www.ads-software.com/Function_Reference/strip_shortcodes)

If we want to respect WordPress excerpt behavior, it would be better to strip them or at least to have a filter to stip them.

It seems to be in this file :

Thanks for your help.
Best,
