code snippet to reproduce:
In src/main.rs:

#[path="parser/__mod.rs"]
mod parser;

fn main() {}

In src/parser/__mod.rs:

mod expr {};

Place the cursor on expr and invoke the "Extract module to file" assist.

Expected behavior:
The line in __mod.rs becomes mod expr;, and a new empty file is created at parser/expr.rs.

Actual behavior:
The line in __mod.rs becomes mod expr;, and a new empty file is created at parser/parser/expr.rs (where it will not be recognized as part of the workspace).
