Navigation Link stores url as id

[gwwar]

After adding a custom link, the block id attribute is set to the url value. In this case we'd expect no id attribute to be set for a custom link.

With work in #31004 we may also want to add the a kind value of custom

Looks like it's coming from

gutenberg/packages/block-editor/src/components/link-control/use-search-handler.js

Lines 22 to 47 in d74e047

	export const handleDirectEntry = ( val ) => {
	let type = 'URL';
	const protocol = getProtocol( val ) || '';
	if ( protocol.includes( 'mailto' ) ) {
	type = 'mailto';
	}
	if ( protocol.includes( 'tel' ) ) {
	type = 'tel';
	}
	if ( startsWith( val, '#' ) ) {
	type = 'internal';
	}
	return Promise.resolve( [
	{
	id: val,
	title: val,
	url: type === 'URL' ? prependHTTP( val ) : val,
	type,
	},
	] );
	};

The type value for a custom link can be URL, mailto, tel or internal

That's 💯 . We definitely do not need an ID for custom. Indeed I've specifically guarded against that case in #31004
