What went wrong

The option g:ale_rust_analyzer_config does not work as described. Related rust-analyzer option rust-analyzer.cargo.features described here.

Reproducing the bug

Add let g:ale_rust_analyzer_config = { 'cargo': { 'features': ['all'] } } to ~/.vimrc.

Edit a rust project with code that enables a feature, e.g.:

#[cfg(feature = "abc")]
mod abc;

ALE/rust-analyzer flags the feature as disabled anyway despite the configuration otherwise.
