UITabBarItem image control when in the "More..." overflow VC

hi all, we are using the UITabBarItem (s) with custom images, works great when the tab bar items are actually in the bottom tab bar, using the special mode of

[... imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

however, when we have overflow tabs that show in the More... view controller, the tab bar images show as a solid rectangle

any tricks to solve this?

see attached, bottom tab is great, but the top More... controller ... not so great
