[Problem/Bug]: FavIcon returned by GetFaviconAsync always blurry

[johanneswanzek]

What happened?

When I use WebView2 "GetFaviconAsync" Method in my App the Favicons are blurry when displayed in larger sizes > 16 px.
I suppose this Method only returns Favicons in 16x16 which is suboptimal for my purpose and I dont want to switch to download the FavIcon manually when I already have this Method.

Is there a chance to make this Method return more quality Favicons?

Repro steps

I am using this code to create the BitmapSource

await using var iconAsStream = await webView.CoreWebView2.GetFaviconAsync(CoreWebView2FaviconImageFormat.Png);
var bitmap = new BitmapImage();
bitmap.BeginInit();
bitmap.StreamSource = iconAsStream;
bitmap.CacheOption = BitmapCacheOption.OnLoad;
bitmap.EndInit();

Icon = bitmap;

This code was also used:
await using var iconAsStream = await webView.CoreWebView2.GetFaviconAsync(CoreWebView2FaviconImageFormat.Png);

var decoder = new PngBitmapDecoder(iconAsStream, BitmapCreateOptions.None, BitmapCacheOption.OnLoad);
BitmapSource bitmapSource = decoder.Frames[0];

Icon = bitmapSource;

Result Image in Size 32x32 px
