Since December 2018, clicking an AMP link from a featured snippet would highlight the exact part of the page that was featured, and now, that same functionality has extended more broadly.
If you’re searching on Google and see a highlighted answer from a featured snippet, opening the website link will now take you directly to the part where the answer shows up and highlight that text in yellow.
A featured snippet and its respective search result highlighted on the page when clicked.
Danny Sullivan, a search liaison at Google, confirms that this feature is now standard for users clicking on HTML and AMP pages from featured snippets.
The official Google Search Liaison Twitter account also confirmed this and added that the scroll anchoring is done using the Scroll To Text Fragment feature for HTML pages on supported browsers.
