### Description

Flood fill works with IM 6.9.13.0 but not IM 7.1.1.22

### Steps to Reproduce

Input:

![f1-7](https://github.com/ImageMagick/ImageMagick/assets/13458218/e06bf5ea-6b6e-4428-849f-af717c2e4ad0)

IM 6:
`convert f1-7.png -fuzz 5% -fill none -draw "matte 275,314 floodfill" -alpha off x-6.png`

![x-6](https://github.com/ImageMagick/ImageMagick/assets/13458218/215fca7e-7de3-42c8-af2a-662c3c99ee04)


IM7:
`magick f1-7.png -fuzz 5% -fill none -draw "alpha 275,314 floodfill" -alpha off x-7.png`

![x-7](https://github.com/ImageMagick/ImageMagick/assets/13458218/beb05fad-62b9-4345-9179-e796a408accd)


Note that the background color from the input should remain in the output, but in IM 7 it is turned black.

**Why do they behave differently? Is that intended?**
