This seems to be a FIXME.

rust-analyzer/crates/ide-diagnostics/src/handlers/inactive_code.rs

Lines 108 to 124 in 634cfe3

	fn inactive_assoc_item() {
	// FIXME these currently don't work, hence the *
	check(
	r#"
	struct Foo;
	impl Foo {
	#[cfg(any())] pub fn f() {}
	//*************************** weak: code is inactive due to #[cfg] directives
	}
	trait Bar {
	#[cfg(any())] pub fn f() {}
	//*************************** weak: code is inactive due to #[cfg] directives
	}
	"#,
	);
