TAdvStringGrid AddBitButton transparency


when adding a button to a grid with grid.AddBitButton, the bitmap’s transparency is not respected, it's being displayed with a white background. The bitmap is read from an imageList by imagelist.getBitmap. The transparent property of the bitmap is set to true.
In the imageList component, the bitmap is properly displayed as transparent.

Any help would be appreciated!
