Autofix on an if statement with a nested if statement using matches breaks

[RDambrosio016]

I tried this code:

if true {
    if matches!(true, true) {
        /* .. */
    }
}

I expected to see this happen (correct autofix):

if true && matches!(true, true) {
    /* .. */
}

Instead, this happened:

if true && match $expression {
            $( $pattern )|+ $( if $guard )? => true,
            _ => false
        } {
    /* .. */
}
