DownloadStarting event not firing when selecting Screenshot > Save from the context menu

What happened?

Run the code and open context menu > Screenshot > Save

Expected behavior:
MessageBox shows and a lossless png, webp or avif is generated that can be directed with ResultFilePath

Actual behavior:
MessageBox does not show and a jpeg file is placed in users download folder

Importance

Moderate. My app's user experience is affected, but still usable.
