Description

Closes #28575

Changes the element structure of the navigation link block in the editor to match the rendered output.

Editor markup:

<nav class="… wp-block-navigation" >
	<ul class="wp-block-navigation__container …">
		<li class="… wp-block-navigation-link" >
			<a class="wp-block-navigation-link__content">
				<div  class="block-editor-rich-text__editable …" contenteditable="true">example.com</div>
			</a></li></ul>
</nav>

Rendered markup:

<nav class="wp-block-navigation">
	<ul class="wp-block-navigation__container">
		<li class="wp-block-navigation-link">
			<a class="wp-block-navigation-link__content" href="http://example.com">
				<span class="wp-block-navigation-link__label">example.com</span>
			</a>
		</li>
	</ul>
</nav>

@jasmussen is it okay that the richtext/textarea is a div instead of span?

@jasmussen is it okay that the richtext/textarea is a div instead of span?

Let me give it a quick spin. I take it the span can't be editable?

So I think I found a few existing accessibility issues while testing with voiceover. If we'd like to tackle this in separate issues, let me know and I can file new tickets.

For folks 👀 , also let me know if certain behavior is expected or if there's alternative keyboard movement controls. (I am aware of keyboard shortcuts, though any richtext or text areas will capture keyboard input).

  1. From the placeholder navigation menu, press enter on the "start empty" element.

Navigation doesn't appear to be selected, I need to tab again.

  1. After adding a link, pressing enter then tab opens publishing settings?

Other keyboard shortcuts for reference.

From a quick test, this looks amazing. Before in the editor:

After in the editor:

The frontend looks the same:

Note, the above is the page list and a custom menu item, and I'm testing using "empty theme": https://github.com/WordPress/theme-experiments. The custom menu item does not have an underline, but that appears to be due to this CSS from #26059:

.wp-block-navigation:not([style*="text-decoration"]) {
	.wp-block-navigation-link__content {
		text-decoration: none;

		&:focus,
		&:active {
			text-decoration: none;
		}
	}
}

Testing my own theme, which styles the a with a box shadow, here's before:

Screenshot 2021-03-17 at 17 22 49

and here's after:

Screenshot 2021-03-17 at 17 26 48

And after is what it's supposed to look like:

Screenshot 2021-03-17 at 17 22 52

In other words, this is working, and the fact that it surfaces that text-decoration rule is an example of why this one is so important to land, because otherwise the CSS we write won't be able to easily affect both the Page List block, custom menu items, and the frontend at the same time, needing 3 separate rulesets. This is being reduced to one ruleset, which is just 👌

Kerry about the keyboard interaction, in some contexts we use tab to switch region or section, and arrowkeys to navigate items within. That may be what's going on here. But just for this PR specifically, I'd compare with what's in trunk. There's certainly still some things we need to get right here, but just important we know whether they're tied to this PR or not.

Thanks @georgeh for looking into this, I think this should be okay to try. I retested on trunk, for keyboard navigation and the issues I found here were also present. I can file a few issues as a follow up.
