While the declarations work perfectly when hovering over their usage in code, each one creates a new line consisting of the bare PHPDoc tag in the class's documentation hover.

    /**
     * This is a foo.
     *
     * @see This other class
     * @method int bar(string baz) Foobar the baz
     * @property string $frob This frobs a little
     * @author David
     */
    class Foo { }

If you hover over Foo you will see

    --------------------------
                   Net/Foo.php
    Foo
    
    This is a foo.
     see      This other class
     method
     property
     author   David
    --------------------------

The "method" and "property" lines should not be there since they're strictly for code-completion. The location relative to other PHPDoc tags--even when there are none--makes no difference.
