AWS CDK Bug - Tags not appearing on external project constructs

Original Issue

🚀 Quick Start

1. Install dependencies for both projects using Yarn v1

cd external-project
yarn install
cd ../main-project
yarn install

2. Run the tests

from /main-project root

yarn test

See failing test

 FAIL  tests/external-project-constructs.test.ts (7.173 s)
  ● Name tag appears on AWS::EC2::VPC, when importing from external project

    Template has 1 resources with type AWS::EC2::VPC, but none match as expected.
    The closest result is:
      {
        "Type": "AWS::EC2::VPC",
        "Properties": {
          "CidrBlock": "10.0.0.0/16",
          "EnableDnsHostnames": true,
          "EnableDnsSupport": true,
          "InstanceTenancy": "default"
        }
      }
    with the following mismatches:
        Missing key at /Properties/Tags (using objectLike matcher)

3. Generate the CloudFormation template

from /main-project root

yarn generate

4. Check the CloudFormation template

Check cdk.out/one-internal-one-external.template.json to see that only the main-project AWS::EC2::VPC has tags and the external AWS::EC2::VPC does not.
