QML Image component doesn't apply devicePixelRatio for network sources

Loading the same image through different urls results in different behavior.

QML Image source:

• "/somefolder/image@2x.png" -> devicePixelRatio = 2.0
• "http://localhost:7000/image@2x.png" -> devicePixelRatio = 1.0
• "http://localhost:7000/image%402x.png" -> devicePixelRatio = 1.0

All variants should result in the devicePixelRatio being 2.0. The URL-encoded variant should also be respected since the "@" symbol is not allowed in the path.
