How are you using Babel?

Programmatic API (babel.transform, babel.parse)

Input code

const traverse = require('@babel/traverse').default;

const code = `
    const {a} = b;
    const {c: d} = b;
    console.log(a);
`

const ast = require("@babel/parser").parse(code);

traverse(ast, {
    Identifier(path) {
        path.scope.rename('a', 'zzz');
    }
});

console.log('a shortahand =', ast.program.body[0].declarations[0].id.properties[0].shorthand);
console.log('c shorthand =', ast.program.body[1].declarations[0].id.properties[0].shorthand);

Output:

a shortahand = true
c shorthand = false

Configuration file name

No response

Configuration

defaults

Current and expected behavior

shorthand not updated, produced AST tree is not valid, shorthand should be set false, when key and value are different.

Environment

latest

Possible solution

Update shorthand when path.scope.rename() called.

Additional context

I trap on this while working on @putout/printer, anyways recast also prints code in the wrong way.
