Repeat on hold not working with Kindle Fire

I am running 1.4.0 on a Kindle Fire running 10.2.1 and when I put my volume buttons in a pinned drawer and specify repeat on hold every .2 sec it does not work it only executes the command once and that is on the release, not the press, of the button. If I take the same button and put it in the panel (not the drawer) it works fine.

I have this exact same setup on my iPad and iPhone with my volume buttons in a drawer and it works fine.

Is this a known issue?
