2. Go to https://www.edition.cnn.com
3. Scroll down to e.g "Feature Sections"

5. After the new page is loaded click back button

The back button should redirect the user to the previous page, to the section where he did the last action

I suspect this is related to scroll anchoring (and race conditions in loading perhaps). You can also see it (many times) by hitting reload on cnn.com, or by going to almost any article and hitting back.

Definitely seems like a regression caused by scroll anchoring. With the feature flag toggled off the back button works as expected and returns to previous section.

I see this on a number of other pages as well (TomsHardware.com, etc). In some cases it simply leaves you noticeably lower on the page than before (perhaps some element (ad?) loads later and moves things?)

This is a duplicate of bug 1524281. I wrote up my thoughts on there.
