Looks like the selection inherits some attributes from the URL after clicking at the end. It should not inherit anything (see: #1016).

Attributes of the text (URL) node:

The code below should also remove attributes that can be added by automatic decorators:

ckeditor5/packages/ckeditor5-link/src/linkediting.js

Lines 519 to 525 in 745d28b

	function removeLinkAttributesFromSelection( writer, manualDecorators ) {
	writer.removeSelectionAttribute( 'linkHref' );

	writer.removeSelectionAttribute( decorator.id );
	}
	}
