"Extract into variable" action not shown when selecting macro invocation

[Nadrieril]

In the following, for some selections the "extract into variable" code action is not listed.

fn main() {
    let x = Some(1);
    let some_condition = false;
    let other_condition = matches!(x, None) || some_condition;
    //                    -----------------                   not listed
    //                   ------------------                   not listed
    //                    ------------------                  listed, but includes the whole expression
    //                    ----------------------------------- listed
    //                                         -------------- listed
}

This fails similarly for other macros (todo, println), with or without arguments.
As a sidenote I find it confusing that selecting a bit of whitespace around an expression ends up selecting more things than just the expression.
