[LayerUtility: ImageRemoveAlpha] Node will not function properly when the Fill Background feature is enabled if the input image has a depth of 32 bits or less.

I tested the images with bit depths of 8, 24, and 32 separately, and only when the input image has a bit depth of 32 does the background filling take effect. The others will produce errors.

8-bit not supported, 24 bit require the input mask of the same size

8 位不支持，24 位需要相同大小的输入掩码

Does that mean my mask has to be 24 bits deep?

The mask only has one channel, so it should be 8-bit
