Rust-Analyzer action `inline macro` doesn't produce valid code

[d4h0]

Summary

Rust-Analyzer action inline macro doesn't produce valid code.

Reproduction Steps

Create a Rust project with a file with the following content:

macro_rules! test {
    () => {
        let foo = 42;
        println!("{foo}");
    };
}

fn main() {
    test!();
}

Move the cursor to test! in the main function, press Space and a to open the code action menu. Now select inline macro.

The macro will be expanded to letfoo=42;println!("{foo}");;, which isn't valid Rust.

(Rust-Analyzer version: rust-analyzer 1 (ff4d55e48 2023-01-15), however that's probably not relevant here)

This is an upstream bug. The same problem occurs in vscode.
Seems similar to rust-lang/rust-analyzer#12860. Best to open a bug report about this in the rust-analyzer repo

I'll close this since it's an upstream issue with nothing to change/update on the Helix side.

For future reference about the log section of the issue template: providing the log can be useful for LSP related bug reports when running in verbose mode (hx -v) since it shows the full communication between Helix and the language server.
