Code block Copy tool doesn't work in http://localhost:1313/influxdb3/cloud-dedicated/get-started/write/?t=v2+API

In the code block for http://localhost:1313/influxdb3/cloud-dedicated/get-started/write/?t=v2+API, the Copy code control throws a console error:

```
code-controls.js:76 Uncaught TypeError: Cannot read properties of undefined (reading 'innerText')
at HTMLLIElement. (code-controls.js:76:28)
```

Open the code block at the provided InfluxDB Cloud Dedicated URL and reproduce the Copy code failure in the browser console. Start with code-controls.js at line 76, where the undefined innerText access occurs. Done means the Copy control copies the code successfully without a console error.
