[Trinidad] tr:icon missing properties?

[Andrew Robinson]

I am trying to use tr:icon. The tag documentation shows support for
events like onclick and properties like inlineStyle. I have created
the icon in my skin:

.AFExpandPanelIcon:alias {
  content: url(/skins/standard/images/icon_expand.png);
}

And then referred to it:

<tr:icon
id="messageHeaderToggleIconExpand"
name="expandPanel"
onclick="expandMessages();"
inlineStyle="display: none;" />

But this is what gets rendered:

<img border="0" src="/context/skins/standard/images/icon_expand.png"
id="messageHeaderToggleIconExpand"/>

This looks like a bug, but before reporting it, wanted to check

Version 1.0.2
