The bug is that if you have some shapes with darker color that you want to fill in-between it doesn’t work if there is a darker background.
In a case like the above image, you can fill the left one successfully but not the right one. The only difference is the color.
If you change the background color to a lighter color both can be filled, so it seems to be only when the background is a darker color.
