No resolutions for a doc link

[simonsan]

Code

Basically this is the module where it fails, right now I can't create a minimized example, I'll try to later:
https://github.com/rustic-rs/rustic_core/blob/057b8acf48caadb23ddc4b51dd032e69cd126cc8/crates/core/src/vfs/webdavfs.rs

Command

cargo +stable doc --no-deps --all-features -p rustic_core
cargo +nightly doc --no-deps --all-features -p rustic_core

on: https://github.com/rustic-rs/rustic_core/
branch: repository-more-access

Meta

Bug also exists on nightly, and also on Linux:
