Anyone get font includes to work in Kodi 18?

Kodi 18 includes the ability to use includes in font.xml.

I’ve been trying to get it to work, but haven’t been successful so far. The include doesn’t seem to be loading, I just get the default font in place of any of the included fonts.

Here’s the basic layout of my font.xml:

Code:
<fontset id="Default" idloc="31390">
        <font>
        </font>
        <include>CommonFonts</include>
</fontset>

The CommonFonts include exists in my includes.xml.

Should it work like this, am I missing something simple? Thanks!

Update: Forgot to mention, I’m running the 64-bit Windows build dated today. Also tested in yesterday’s 32-bit build with the same results.
