Subject: [PATCH 1/2] Add missing css.properties.display.none.option_is_hidden
 feature

This PR adds the missing `none.option_is_hidden` member of the `display` CSS property. The data comes from manual testing, running test code through BrowserStack, SauceLabs, custom VMs and/or locally.

Test Code:

```html
<style id="test-style">
	#hidden {
		display: none;
	}
</style>
<select>
	<option>One</option>
	<option id="hidden">Two</option>
	<option>Three</option>
</select>
```

Additional Notes: This fixes #24247.
