Angle brackets escaped when sent over the wire

It seems Movim is sending > and < as XML entities (or rather, what would be displayed as XML entities) on the wire. I have only noticed it in replies for now, I don't know if it happens in normal messages or anything.

As seen from poezio:

According to slixmpp, Movim sent the following, note the &amp:

&gt; &amp;gt; edhelas:
&gt; &amp;gt; _I found the issue. Issue was even before i have not set `pep_max_items` value i have used movim and the issue is movim client set my PEP value as *default to 1.*_
&gt; &amp;gt; _even if i change value on server. The Movim client still keeps it in value *1*._
&gt; &amp;gt; _So is there any client or any way i can manage to edit my PEP value of Movim?_
&gt;
&gt; edhelas: Any comments for this. :)
So prosody ?</body>
