text in the chat is displayed immediatly at some point

I reproduced the bug.
I do the mission 'Looking for a missing agent - part one'
I reach the point where the chat says : "Can you find more about this? When you have an idea, type it in the field on the bar and press enter"
Then I type 'last supper' in the url bar.
The the web page loads, and the complete following text is displayed at once :
"Yes, that seems right
EagleOneBut, I have no clue what to do with this
EagleOneHmm, what else do we know ? Ah yes, it was sent last monday afternoon. Let's look at that part, ok ?"

Sometimes, it happens immediatly, sometimes in two steps with first a blank screen and then the 'connecting' visual that pops up, but in both cases I see the complete text immediatly there.

I reproduced it with a long text, by replacing the function painting() in agent_partone.php with :

    function painting() {
             $game_session = GameSession::getInstance('','',array());
  if (ereg("last supper",$game_session->site->url)||ereg("Last Supper",$game_session->site->url)) {
   $this->say("Yes, that seems right");
   $this->say("But, I have no clue what to do with this");
   $this->say("Hmm, what else do we know ? Ah yes, it was sent last monday afternoon. Let's look at that part, ok ?");
   $this->say("Hmm, what else do we know ? Ah yes, it was sent last monday afternoon. Let's look at that part, ok ?");
   $this->say("Hmm, what else do we know ? Ah yes, it was sent last monday afternoon. Let's look at that part, ok ?");
   $this->say("Hmm, what else do we know ? Ah yes, it was sent last monday afternoon. Let's look at that part, ok ?");
   $this->say("Hmm, what else do we know ? Ah yes, it was sent last monday afternoon. Let's look at that part, ok ?");
   $this->say("Hmm, what else do we know ? Ah yes, it was sent last monday afternoon. Let's look at that part, ok ?");
   $this->say("Hmm, what else do we know ? Ah yes, it was sent last monday afternoon. Let's look at that part, ok ?");
   $this->say("Hmm, what else do we know ? Ah yes, it was sent last monday afternoon. Let's look at that part, ok ?");
   $this->say("Hmm, what else do we know ? Ah yes, it was sent last monday afternoon. Let's look at that part, ok ?");
   $this->say("Hmm, what else do we know ? Ah yes, it was sent last monday afternoon. Let's look at that part, ok ?");
   $this->say("Hmm, what else do we know ? Ah yes, it was sent last monday afternoon. Let's look at that part, ok ?");
   $this->say("Hmm, what else do we know ? Ah yes, it was sent last monday afternoon. Let's look at that part, ok ?");
   $this->say("Hmm, what else do we know ? Ah yes, it was sent last monday afternoon. Let's look at that part, ok ?");
   $this->say("Hmm, what else do we know ? Ah yes, it was sent last monday afternoon. Let's look at that part, ok ?");
   $this->say("Hmm, what else do we know ? Ah yes, it was sent last monday afternoon. Let's look at that part, ok ?");
