vertical align text/button in 2 column section

I am trying to vertically align some text and a button with a 2 column section. To clarify my goal is to have the text/button to align with the vertical middle of the image to it's right.

I have tried adding the vertical-align="middle" tag to the mj-column but this does not seem to have any effect. However, aligning to the bottom does work.

Below is a sample of my code and a link to the mjml editor with a sample demonstrating the issue.

<mjml>
  <mj-body>
    <mj-section>
      <mj-divider border-color="#F45E43"></mj-divider>
      <mj-column width="50%">
        <mj-image src="http://www.online-image-editor.com//styles/2014/images/example_image.png" />
      </mj-column>
      <mj-column width="50%" vertical-align="middle">
        <mj-text align="center">Want a kitten? Of course you do! Who doesn't want a fluffy little buddy to keep you company? Go on click the button, you know you want to.</mj-text>
        <mj-button href="https://www.google.com">Get a Kitten</mj-button>
      </mj-column>
      <mj-divider border-color="#F45E43"></mj-divider>
    </mj-section>
  </mj-body>
</mjml>
