Doc links containing generic parameters aren't resolved

[SludgePhD]

rust-analyzer version: 0.3.1860-standalone

rustc version: current stable, but shouldn't matter much

code snippet to reproduce:

//! [`Vec`] and [`Vec<T>`].

Here, Vec gets highlighted and resolved correctly, but Vec<T> does not, even though rustdoc accepts it without warnings and turns both into links to the same page.
