Cannot get bemenu to be transparent

[UtkarshVerma]

I want to set an alpha for bemenu's background to achieve that glassy look. Setting any value for A in RGBA for normal background, but I can't get it to be translucent.

Setting A to 00 just gives me a black background instead of completely making bemenu see-through. Is it possible?

Works for me on wayland and x11 (v0.6.9 and master) using --nb #000000
