title: Order confirm email translation issue Magento 2
body: <p>Our Magento 2.1.5 site is ready to translate all email templates.
  But, when a customer creates order, he got non-translated order confirm email immediately. To check this issue, when we click "send email" tab on order view page on admin, we get the correctly translated email.</p>
  
  <p><a href="https://i.stack.imgur.com/8Pvcl.png" rel="nofollow noreferrer">Send order</a></p>
  
  <p>What was wrong?</p>
  
  <p>We found this email template which was just order_new.html on theme folder.</p>
  
  <pre><code>app\design\frontend\[vendor]\[theme]\Magento_Sales\email\order_new.html
  </code></pre>
  
  <p>Also, this template was assigned on vendor.</p>
  
  <pre><code>vendor\magento\module-sales\etc\email_templates.xml
  
  &lt;template id="sales_email_order_template" label="New Order" file="order_new.html" type="html" module="Magento_Sales" area="frontend"/&gt;
  </code></pre>
  
  <p>Is there any solution?</p>
