Incorrect Tile Rendering

[vulpivia]

A tile is expected to render with palette indices of all zeros but instead appears with the following indices:

1, 65, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0,

Code:

#[agb::entry]
fn main(mut gba: Gba) -> ! {
    let mut mgba = Mgba::new();
    let vblank = VBlank::get();
    vblank.wait_for_vblank();

    let (tiled0, mut vram_manager) = gba.display.video.tiled0();

    vram_manager.set_background_palette_raw(&PALETTE);

    let tile_set = TileSet::new(
        &[
            0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
            0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
            0, 0, 0, 0, 0, 0,
        ],
        TileFormat::EightBpp,
    );
    let mut loan = tiled0.background(
        Priority::P0,
        RegularBackgroundSize::Background32x32,
        TileFormat::EightBpp,
    );
    loan.set_tile(
        &mut vram_manager,
        (0_u16, 0_u16),
        &tile_set,
        TileSetting::new(0, false, false, 0),
    );
    loan.deref_mut().commit(&mut vram_manager);
    loan.deref_mut().set_visible(true);

    loop {}
}

The palette I used, in case it matters:

Nevermind, seems to work with the current master branch, just not with v0.21.3.
