[bug] mako doesn't working with @opensumi/di 's example

[stormslowly]

package.json

{
       "name": "dead-simple",
       "dependencies": {
               "@opensumi/di": "^2.1.0",
               "reflect-metadata": "^0.2.2"
       }
}

src/index.ts

import "reflect-metadata"

import { Injectable, Autowired, Injector } from '@opensumi/di';

interface Drivable {
  drive(): void;
}

@Injectable()
class Bike implements Drivable {
  drive() {
    console.log('Bike is driving');
  }
}

@Injectable("Student")
class Student {
  @Autowired('Drivable')
  mBike: Drivable;

  goToSchool() {
    console.log('go to school');
    this.mBike.drive();
  }
}

const injector = new Injector();
injector.addProviders(
  { token: 'Drivable', useClass: Bike },
  { token: 'Student',  useClass: Student }
);

const student = injector.get('Student');
student.goToSchool(); 

expect log

go to school
Bike is driving

but error

                    this.mBike.drive();
                               ^

TypeError: Cannot read properties of undefined (reading 'drive')

原因
mako 使用默认的 assumption 配置

assumption.set_public_class_fields = false;
assumption.set_class_methods = false;

相当于 swcrc 配置 ref

  "transform": {
      "legacyDecorator": true,
      "useDefineForClassFields":true <----- here

产物中

class Student {
    mBike;  <-----   直接覆盖了 decorator 结果
    goToSchool() {
        console.log('go to school');
        this.mBike.drive();
    }
}

修改 useDefineForClassFields -> false

产物正常执行
