I have no idea about DIB code, but just from the commit message I
presume that this change to 24 bits has happened deliberately.
Probably, but that doesn't make it correct ;-)
The MaskBlt tests show that we should apply the operation on all 32 bits.
Also it will be applied on the bits of mono bitmaps, which can lead to
undesired results if 3/4 of the pixels are simply black. Please have a
look at 2nd stage installer (disabled buttons)
