What happened?

using git head

let icon = Icon::from_file_data(icon_data, Some(image::ImageFormat::Png));

returns

Ok(
    Icon(
        NoIcon,
    ),
)

from https://github.com/rust-windowing/winit

/// For platforms which don't have window icons (e.g. web)
#[derive(Debug, Clone, PartialEq, Eq)]
pub(crate) struct NoIcon;

    impl NoIcon {
        pub fn from_rgba(rgba: Vec<u8>, width: u32, height: u32) -> Result<Self, BadIcon> {
            // Create the rgba icon anyway to validate the input
            let _ = RgbaIcon::from_rgba(rgba, width, height)?;
            Ok(NoIcon)
        }
    }

rustc 1.64.0 (a55dd71d5 2022-09-19)

What is the expected behavior?

let icon = Icon::from_file_data(icon_data, Some(image::ImageFormat::Png));

returns an icon and the window shows it
