Expected vs Current Behavior

Expected: Open MCT should open a new browser tab and navigate to the telemetry used in the Data Visualization.
Current: console error

Steps to Reproduce

1. See instructions for Data inspector visualization missing renderWhenVisible #7283
2. Use the Open In New Tab as seen in the attached below screenshot
3. Should see expected behavior above

Environment

• Open MCT Version:
• Deployment Type:
• OS:
• Browser:

Impact Check List

• Data loss or misrepresented data?
• Regression? Did this used to work or has it always been broken?
• Is there a workaround available? Just go to the telemetry, or use the Open In New Tab action from the tree
• Does this impact a critical component?
• Is this just a visual bug with no functional impact?
• Does this block the execution of e2e tests?
• Does this have an impact on Performance?
