Inconsistent macro parsing between rust-analyzer and rustc

rust-analyzer version: (eg. output of "rust-analyzer: Show RA Version" command, accessible in VSCode via Ctrl/⌘+Shift+P)

rustc version: 0.4.2885-standalone

editor or extension: VSCode

relevant settings: None

repository link (if public, optional): https://github.com/bevyengine/bevy/issues/24050. See https://github.com/alice-i-cecile/bevy/tree/negative-captain for a branch with a ready-made reproduction.

code snippet to reproduce:

use bevy::prelude::*;

        #[derive(Component, FromTemplate, PartialEq, Eq, Debug)]
        struct Foo {
            x: i32,
        }

        fn scene() -> impl Scene {
            bsn! {
                Foo { x: -42 }
            }
        }

Note: requires the currently unreleased Bevy 0.19 or later!

Start with the reproduction in the linked Bevy issue and the negative-captain branch, using the supplied rust-analyzer and rustc versions. Compare how each parses the bsn! macro example involving the negative literal. Done means the inconsistent parsing behavior is identified and rust-analyzer matches rustc for this reproduction.
