XML entity rendering not working#941

Instead of displaying the proper text, Text elements display raw XML.

For example,

<Button
   width="300" height="40" rectAlignment="UpperLeft" offsetXY="100 -5"
   allowDragging="true" returnToOriginalPositionWhenReleased="false"
>
      <Panel width="255" height="30" rectAlignment="MiddleLeft" offsetXY="5 0">
         <Text fontStyle="Bold" fontSize="16" color="Black">LT: &lt; GT: &gt; AMP: &amp;</Text>
      </Panel>
</Button>

results in a button with text

LT: < GT: > AMP: &

instead of the correct

LT: < GT: > AMP: &

In fact, it seems impossible to create a button with the latter text.

“Text elements display raw XML” would be a better title. I can’t edit it.
