Window palette colors incorrectly interpreted

What steps will reproduce the problem?
1. Load the following palette for Metroid 2 (not DX!):
    <bkgr c0="0xFFFFFF" c1="0x63A5FF" c2="0x0000FF" c3="0x000000" />
    <wind c0="0xFFFFFF" c1="0x63A5FF" c2="0x0000FF" c3="0x000000" />
    <obj0 c0="0xFFFF00" c1="0xFF0000" c2="0x630000" />
    <obj1 c0="0xFFFFFF" c1="0x7BFF31" c2="0x008400" />

2. Notice that status/health bar at bottom of screen has disappeared (where it 
shows energy and missile numbers).  Switch back to monochrome to verify how 
it's supposed to look like.
3. Under the window palette, change any of the c3 levels to any valid value, 
for instance, c3="0x000000", and the white bar will return, regardless of the 
value chosen.  The white bar will now persist until you quit VBA GX, even if 
you change the game and then go back to Metroid 2, and even if you change c3 to 
all zeroes.

What is the expected output? What do you see instead?
The white bar is dictated by c0, which is set to FFFFFF, so it should show up 
as white, independently of the color chosen for c3.

Does this issue occur on VBA-M r781 -

If so, please report the issue to the VBA-M forum.
This is a VBA GX specific feature.

What version are you using? On GameCube or Wii?
Wii, 2.2.2

Are you using the official build (from the downloads page or auto-update)?
Yes, downloaded from here.

Please provide any additional information below.
That palette, simply rocks.  It is the original Gameboy Color built-in palette 
for the old monochrome Metroid 2 Gameboy cartridge.  This chap has been 
extracting the palettes from the GBC bootrom and posting them here:

The palette for Metroid has a lot of visual pop and is bright and colorful and 
I've never seen this old game look better.
Kudos to Tantric and Karl for allowing this level of output control.
