 With a directive like the following:

 {{{
 <div data-wp-bind--hidden="!state.missing.property">
         This should be hidden by the <code>hidden</code> attribute.
 </div>
 }}}

 The server will render the following HTML:

 {{{
 <div data-wp-bind--hidden="!state.missing.property">
         This should be hidden by the <code>hidden</code> attribute.
 </div>
 }}}

 But the client will immediately set the `hidden` attribute (the expected
 behavior):

 {{{
 <div data-wp-bind--hidden="!state.missing.property" hidden="">
         This should be hidden by the <code>hidden</code> attribute.
 </div>
 }}}

 The client and server should align on the behavior of the negation
 operator with directives to missing paths.
