Rustdoc - Section Symbol in Wrong Location on Impls w/ Where Clauses

[Havvy]

Real time example: Hover over this impl on vec.

The section symbol appears on its own line instead of somewhere on the impl itself.

Hum... Do you have an idea since when? It could help to understand where the issue is coming from instead of just fixing it.

[Havvy]

I don't know when it started. I don't remember the last time I looked at the nightly docs. Tuesday was the latest possible time, but 🤷‍♂️.

@GuillaumeGomez The § thing doesn't appear in beta, so likely a bug in the initial implementation (I guess #43747).

[ollie27]

#43979 added the § for impls.

Thanks @ollie27! Taking a look this evening.
