If you enter the following macro text (into a template or a new page), you will find that the HTML is rendered as wki text rather than wiki text.
<<<<< Macro text >>>>>
{composition-setup}
Definition{show-if:action=view} {toggle-cloak:id=HelpRMDefinition}
{cloak:id=HelpRMDefinition}
{tip:icon=false}
Help for Definition.
The definition that you enter below is what will be shown on reports and tables within the Reference Model and any views that refer to it.
It is best that you keep your definition reasonably succinct and place the extra details in the Extra Information field below.{tip}{cloak}{show-if}
<<<<< Macro text >>>>>
The rendered text is shown below:
<<<<< Rendered text >>>>>
Definition <span id='tgl_content_HelpRMDefinition' class='cloakToggle'></span>
<span id='content_HelpRMDefinition' class='cloak' style='display: none'>
<div class='panelMacro'><table class='tipMacro'><tr><td><img class="emoticon" src="/confluence/images/icons/emoticons/help_16.gif" height="16" width="16" align="absmiddle" alt="" border="0"/> Help for Definition. <br clear="all" /> <br clear="all" />
The definition that you enter below is what will be shown on reports and tables within the Reference Model and any views that refer to it.

If you remove the {show-if} macro, the wiki text is rendered correctly.
