I'm not sure if this change is intentional or not, but I thought it's worth reporting in case it's a bug.

cc @rust-lang/rustdoc: Was this change intentional?

I don't think so!

We found it out with @dns2utf8 and we weren't sure whether it was good or not (from a "look" point of view) and simply decided to wait and see if people liked it or not. So, should we revert it or not? :)

As a random person on the internet, I prefer the old look better. Although I admit that's at least partially due to familiarity with it.

Assigning priority as discussed in the Zulip thread of the Prioritization Working Group.

[Manishearth]

@GuillaumeGomez I would revert it

[GuillaumeGomez]

I'll change the look then.
