Describe the bug Fails to load bitmap in 0.10.11, 0.10.12 and 0.10.13. Succeeds in 0.10.10 and earlier.

I believe it is due to using SkiaSharp 2.88.0-preview.178 since 0.10.11: https://github.com/mono/SkiaSharp/issues/1752 https://github.com/mono/SkiaSharp/issues/1551

To Reproduce

using (var memoryStream = new MemoryStream(path)) {
    var bitmap = Bitmap.DecodeToWidth(memoryStream, 80); 
}

Desktop (please complete the following information):

• OS: Windows 10
• Version 0.10.13

Probably fixed by: https://github.com/mono/SkiaSharp/pull/2045

Would it be possible to implement the workaround suggested by @AndersMad in https://github.com/mono/SkiaSharp/issues/1551#issuecomment-756685252? Because that seems to solve the issue, and it doesn’t look like SkiaSharp will fix the underlying bug anytime soon. I didn’t create a PR because I don’t know what (performance) implications this change might have.
