Intel XDK App Framework textarea gets focus only on every second tap

Question

I have a typical textarea in my panels:

<textarea name="textarea12"
          data-object-id="12"
          id="textarea12"
          cols="30"
          rows="10">
</textarea>

It only gets focus on the second tap/click/touch. The annoying thing is that when I inspect it in the Intel XDK debugger, it does get the class 'pressed' on every tap but it only gets focused on every second one.

Why does this happen?
