I am developing my own step plugin in java. Is it possible to pass a string that contains an HTML code in the setErrorMessage() method?. So the message is displayed as HTML text in the error message panel
I have tried the following

setErrorMessage("Some plain text and some <b> bold text </b> \r\n");
or 
setErrorMessage("Some plain text and some &lt;b&gt; bold text &lt;/b&gt; \r\n");

But both do not work! The text "bold text" is not displayed bold.
Only the \r\n is displayed as a <br> in the source text.
