It used to be like that when they still used "/url?..." redirect links, which have the destination URLs clearly exposed. Maybe it's an intended feature for checking out where does the link leads to. That behavior can be prevented by browser extensions.
Now, on desktop Firefox (private browsing mode, logged out), I see that it always links to the opaque goto URLs, instead of only overwriting on interaction.
Using Google Search while logged in on Chrome Android still presents the older non-opaque /url?... links though.
It's unfortunate that we cannot immediately inspect what the link will lead to, whether the link is the intended (and safe/expected) destination or not.
