<select> elements with no label not picked up as an error

Consider the following minimal HTML page:
```html

Bad form

```

Neither the `input` nor the `select` have a label of any kind. However, Lighthouse Accessibility only picks up the `input`:

If I run the Axe extension over the page directly, it picks up two _different_ errors, "Form elements must have labels" and "Select element must have an accessible name":

but Lighthouse is only reporting the first of these. It should report both.

Start by running Lighthouse Accessibility against the minimal HTML reproduction and compare its findings with the two errors reported by the Axe extension. Trace the accessibility audit responsible for form labels, then confirm done when the unlabeled input and select are both reported as expected.
