HTML output discards @othertype note titles

[infotexture]

Given a <note> of @type=other, the user-specified note title defined in the @othertype attribute is missing in HTML output, but retained in PDF output.

<note type="other" othertype="Update">Note text.</note>

This renders as expected in PDF:

Update: Note text.

In HTML output, the note title is missing:

    : Note text.

The generated HTML source reveals that the @othertype attribute is included on the <span> element, but only the colon character appears in the span content:

<div class="note note note_note">
  <span class="note__title notetitle" othertype="Update">:</span> Note text.
</div>

I think this one is obsolete - when I have anything in the @othertype attribute, it appears in both XHTML and HTML5 using the same style as other note elements. In both cases:
<note type="other" othertype="My other type">other note here</note>
results in
My other type: other note here
