title: Rails form helper number_field_tag size option not working in Rails 4?
body: <p>I'm using Rails 4.1.1, Ruby 2.1.2, Twitter Bootstrap (bootstrap sass gem) 3.0.3. <code>Number_field_tag</code> shows the same size no matter what I set the <code>size</code> option to per the documentation saying that it can take the same options as <code>text_field_tag</code> (which has a <code>size</code> option).</p>
  
  <p>Incidentally, just to test, I tried a <code>text_field_tag</code> and the <code>size</code> option works fine. Anyone know the fix here? I'm happy to use a CSS class to achieve the same effect, but why write extra code right?</p>
  
  <p>Also note, when I inspect element, <code>size</code> is showing up, it's just not doing anything:</p>
  
  <pre><code>&lt;input id="transaction__Portable_table" min="0" name="transaction[][Portable table]" size="1" type="number" value="0"&gt;
  </code></pre>
