1. Go to the PAL progress indicator: https://next.carbon-addons-iot-react.com/?path=/story/1-watson-iot-progress-indicator-progress-indicator--stateful
2. Select the last step.
3. Notice the horizontal or vertical line on the last step.

Expected behavior

There should be a horizontal/vertical line which should bleed full length.

• OS: All
• Browser: All
