Poor completion in tracing crate macros

[SludgePhD]

rust-analyzer version: 0.3.2220-standalone

rustc version: any recent

editor or extension: VSCode, but shouldn't matter

relevant settings: none

repository link (if public, optional): https://github.com/tokio-rs/tracing

code snippet to reproduce:

let variable = "test";
tracing::info!(var<|>);
tracing::info!(name = var<|>);

Requesting completions in the two places in the snippet above comes up empty, but this is a valid place to put the variable local, which tracing will then emit as an event.

let variable = "test";
tracing::info!("{}", va<|>);

In this snippet, the info! macro is used just like log::info! can be, except with the log crate, rust-analyzer does manage to provide proper completions.

A fix for these would be great, since tracing is heavily favored over log in large parts of the ecosystem (eg. the whole async ecosystem, and bevy uses it too).

Minimized:

macro_rules! helper {
    ($v:ident) => {};
}

macro_rules! m {
    ($v:ident) => {{
        helper!($v);
        $v
    }};
}

fn main() {
    let variable = "test";
    m!(v|);
}
