sequence<> in constructor argument not properly escaped

[dontcallmedom]

<dl class="idl"
title="[Constructor,
Constructor (MediaStream stream),
Constructor (sequence&lt;MediaStreamTrack&gt; tracks)]
interface MediaStream : EventTarget">
does not escape the parameter of the sequence type in the generated output

Another bogus report, this was because the constructors were defined in the title, whereas they are expected to be defined as dt/dd pairs.
