Some TIFF images with alpha decoded incorrectly

[Shnatsel]

This happens in image v0.24.2

Actual behaviour

The attached files are rendered differently by image compared to imagemagick and GIMP. Specifically, the yellow color in the bottom right corner is different.

Expected

No discrepancies

Reproduction steps

use std::error::Error;

fn main() -> Result<(), Box<dyn Error>> {
    use image::io::Reader as ImageReader;
    let input = std::env::args().nth(1).unwrap();
    let output = std::env::args().nth(2).unwrap();
    
    let img = ImageReader::open(input)?.decode()?;
    img.save(output)?;
    Ok(())
}

invoked with image-convert in.tiff out.png
