Invalid template metadata labels generated

Description of the bug:

Consider the following cdk8s code:

import { Construct } from 'constructs';
import * as kplus from 'cdk8s-plus-22';
import { Chart, ChartProps } from 'cdk8s';

export const PodLabels = {
  'custom-label-1': 'value1',
  'custom-label-2': 'value2',
  'custom-label-3': 'value3',
};

export class TestChart extends Chart {
  constructor(scope: Construct, id: string, props: ChartProps = { }) {
    super(scope, id, props);

    const deployment1 = new kplus.Deployment(this, 'deployment1', {
      metadata: {
        name: `${id}-deployment1`,
        namespace: 'testns',
      },
      podMetadata: {
        labels: PodLabels,
      }
    });
    deployment1.addContainer({
      image: 'paulbouwer/hello-kubernetes',
      port: 8080
    });

    const deployment2 = new kplus.Deployment(this, 'deployment2', {
      metadata: {
        name: `${id}-deployment2`,
        namespace: 'testns',
      },
      podMetadata: {
        labels: PodLabels,
      }
    });
    deployment2.addContainer({
      image: 'paulbouwer/hello-kubernetes',
      port: 8080
    });
  }
}

The following template is generated where there’s invalid label cdk8s.deployment: testchart-deployment2-c87e348b under the deployment 1.

@Chriscbr can you reopen the ticket or do I have to file a new one?

Thanks, Markus

@markusl I’m not actively working on cdk8s at the moment, so I don’t think I can help. @iliapolo might be able to answer, otherwise I’d try asking on the cdk.dev slack. 🙏
