Post previews in Telegram

This is what Telegram is looking at:

<link rel="canonical" href="https://meta.discourse.org/t/preparing-for-discourses-upgrade-to-ember-5/287211?page=3" />

Which links to: Preparing for Discourse's upgrade to Ember 5 - #48 by david

This is matching with the content Telegram is fetching as seen in my screenshots

EDIT - this post from 2022 seems related.
