The qualified name provided ('clipPath"') contains the invalid character '"'.

Trying to render [@stdlib/plot](https://github.com/stdlib-js/stdlib/tree/develop/lib/node_modules/%40stdlib/plot/ctor) with `nanohtml`

```js
import Plot from '@stdlib/plot/ctor'
import html from 'nanohtml'
let plot = new Plot([[0,1,2]], [[0,2,1]])
document.body.appendChild(html(plot.render('html')))
```

getting
```sh
Uncaught (in promise) DOMException: Failed to execute 'setAttributeNS' on 'Element': The qualified name provided ('clipPath"') contains the invalid character '"'.
```

The HTML generated by `plot` is

```html

```

Start with the supplied nanohtml reproduction using Plot.render('html') and inspect how SVG elements and namespaced attributes are created. Reproduce the setAttributeNS error in a browser, then verify that the same rendered plot can be appended without the invalid qualified name exception.
