RA error remains on commented-out line

[reisnera]

rust-analyzer version: rust-analyzer version: 0.4.2248-standalone [/home/alex/.vscode/extensions/rust-lang.rust-analyzer-0.4.2248-linux-x64/server/rust-analyzer]

rustc version: rustc 1.83.0 (90b35a623 2024-11-26)

editor or extension: VSCode extension 0.4.2248

relevant settings: "rust-analyzer.check.command": "clippy"

code snippet to reproduce:

fn go() -> Vec<u32> {
    let v: Vec<u32> = Vec::new();
    // v.iter()
    v
}

If I take the above snippet and uncomment the commented line, I understandably get an error. If I recomment it without saving, it goes away. If I uncomment the line and then save, the RA error persists no matter what I do, and I would have to re-comment the line and reload RA to get it to return to normal.

I think I'm hitting this error extremely frequently in more complicated cases that don't involve commented lines, but I'm starting here...

I have got the same issue. Downgrading to 0.3.2247 does not work. Downgrading to 0.3.2237 fixes the issue
