getByRole('deletion') does not return matching <s> element

[tomalexhughes]

• @testing-library/dom version: 10.4.0
• Testing Framework and version: jest 28.1.3
• DOM Environment: jsdom 16.7.0

I believe this is framework/environment agnostic as the same happens using @storybook/test.

Relevant code or config:

// React Component
const StrikethroughText = () => <s>Strikethrough Text</s>

// Test File
screen.getByRole('deletion')

What you did:

Attempted to use a getByRole query to target an <s> element.

What happened:

An error was thrown that an element could not be found.

Reproduction:

Problem description:

The HTML ARIA spec states an s element has an implicit role of deletion, and it is not recommended to add this as an explicit role.

However, *ByRole queries only find the element if the role is explicitly set.
