### Product

axe Extension

### Product Version

axe DevTools for Firefox, 4.49.0

### Latest Version

- [X] I have tested the issue with the latest version of the product

### Issue Description

#### Expectation

An aria-label attribute on an svg image element should not trigger an error.

#### Actual

axe dev tools reports a error (of level "serious") with the message: "aria-label attribute cannot be used on a image with no valid role attribute."

#### How to Reproduce

```html

axe svg image aria-label

Image test

```

#### Additional context

From a quick test, chromium and webkit appear to follow the svg-aam and expose svg image elements correctly with role `img` and `image` respectively when an aria-label is present.

While Firefox seems to expose the image element with a strange role of "nothing", the label seems to be exposed -- orca, jaws and narrator voice it even if NVDA fails. (For completeness, Narrator fails to voice the label on Chrome.)
