Aligns on the behavior of the negation operator with directives to missing paths in client and in server.
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>
}}}
Both server and client will return with this fix:
{{{
<div data-wp-bind--hidden="!state.missing.property" hidden="">
This should be hidden by the <code>hidden</code> attribute.
</div>
}}}
Props jonsurrell, luisherranz.
