title: geocode component filtering with field "locality" not working as expected
body: <p>I'm using Google Map's Geocode API to get the lat, lng values for this address in Manhattan:
  <code>123 Dr Martin Luther King Jr Blvd, New York, NY 10035, USA</code></p>
  
  <p>My initial query looks like this: <a href="https://maps.google.com/maps/api/geocode/json?address=123%20mlk%20blvd" rel="nofollow noreferrer">https://maps.google.com/maps/api/geocode/json?address=123%20mlk%20blvd</a></p>
  
  <p>This query does not return my desired address, so in order to filter down results to only those in Manhattan I modified by request to include the Component Filtering parameter <code>locality:Manhattan</code>.</p>
  
  <p>As defined in the docs here: <a href="https://developers.google.com/maps/documentation/geocoding/intro#ComponentFiltering" rel="nofollow noreferrer">https://developers.google.com/maps/documentation/geocoding/intro#ComponentFiltering</a></p>
  
  <p>So my question is - why does this url: <a href="https://maps.google.com/maps/api/geocode/json?address=123%20mlk%20blvd&amp;components=locality:Manhattan" rel="nofollow noreferrer">https://maps.google.com/maps/api/geocode/json?address=123%20mlk%20blvd&amp;components=locality:Manhattan</a> not return my desired address?</p>
  
  <p>And yet - using the component filter <code>postal_code:10035</code> does return my desired address: <a href="https://maps.google.com/maps/api/geocode/json?address=123%20mlk%20blvd&amp;components=postal_code:10035" rel="nofollow noreferrer">https://maps.google.com/maps/api/geocode/json?address=123%20mlk%20blvd&amp;components=postal_code:10035</a></p>
  
  <p>Thanks</p>
