Multi cursor postfix snippets only work correctly for the first cursor

rust-analyzer version: bc08b8eff 2022-03-28 stable

rustc version: 1.58.1 (db9d1b20b 2022-01-20)

relevant settings: N/A

match result {
    Some(_) => {
        assert!(wip.is_empty());
        /* ... */
    },
    None => {
        assert!(wip.is_empty());
        /* ... */
    }
};

In code above I want to quicky invert the assert conditions, so I select the first wip.is_empty() and select the next occurence with Ctrl+D. Then I type .not at the end and press enter.

The result is

match result {
    Some(_) => {
        assert!(!wip.is_empty());
        /* ... */
    },
    None => {
        assert!(wip.is_empty().!wip.is_empty());
        /* ... */
    }
};

(This may be an issue with VS Code, but I don't know how to tell. If so I can close this and report it to VS Code)

Reproduce the issue in VS Code with the Rust snippet, two cursors, and the .not postfix snippet. Determine whether the incorrect second expansion belongs to rust-analyzer or VS Code; done means both selected occurrences expand correctly without duplicating text.
