Bug in rendering HTML content Apex 2.2 (in Apex 2.0 was OK)

Question

We have many PLSQL processes which are called through boolean function which return some message as well as the result.
<br>
function some_func (pid IN NUMBER,err_msg OUT NOCOPY VARCHAR2) RETURN BOOLEAN;<br>
and at the end function looks like:
<br>
  :err_msg := 'Pitanje <*b>'||TO_CHAR(p_id)||'<*/b> je OK!';
  RETURN TRUE;<br>
Later, in "On load before header", we call this function and assign "err_msg" value to hidden item "P2_MESSAGE", placed on the same page. Assigment is done in an way like:
<br>
  some_bool:=some_func (:P2_ID,:P2_MESSAGE);<br>
In one HTML reagion, we put in "Source", code like:
<br>
<*class="t16dataalt">&P2_MESSAGE.</class><br>
and until now, bold tags are applied as well as class-we get only text!
<br>
But now, in Apex 2.2, (original theme 16 used) in result we get all content as it is not recognized as HTML code.
<br>
In browser the result(in a case of OK result) is:
<br>
Pitanje <*b>1<*/b> je OK!<br>
and the generated source is:
<br>
<*class="*t16dataalt">Pitanje &*lt;*b&*gt;1&*lt;/b&*gt; je OK!</*class="*t16dataalt"><br>
Is that a bug or what?
<br>
Once more, before the same code was working nice, theme 2 used...
<br>
THX!
<br>
P.S
<br>
"*" is added to be read clearly!
<br>
P.S II
<br>
We have imported app that was exported on Apex 2.0 and the same problem occure!
<br>
So we think this is a bug in rendering HTML region!
<br>
Is there any hint to overcome that until patch come ?

The issue is easy to reproduce. Create HTML region:
User Interface Template-Reports Region
Display point-Page template body
Assign one hiden item in on load process with value:
P2_MESSAGE := "< b>OK</ b<>";
Put P2_MESSAGE in HTML Source with content like this:
< class="t16dataalt">&P2_MESSAGE.</ class>
and you have it!
