urls in QDropEvent is not correct when drag and drop file from WSL2 network location to Qt widget

When drag and drop file from windows explorer which opened a WSL2 location to a Qt based app, urls from event->mimeData()->urls() in dropEvent(QDropEvent *event) are always missing the hostname and no way to obtian the original url.

To reproduce:

• Prepare a Windows system with WSL2(Windows Subsystem for Linux 2) subsystem.
• Prepare a Qt application which accept file drop and print the URL which dropped on top of that widget/application.
• Open any WSL2 network location, and drag the file to the Qt application. (example path: \\wsl$\Ubuntu\home\username\filename.png)
• See the print. (for the example location, the hostname part wsl$ will be disappeared.

Probably related to QTBUG-86277 but I'm not quite sure. Although wsl$ is not a valid hostname, but since when DnD the url are get handled by Qt internal, so seems no way to workaround. Expecting a way to obtian correct file url for DnD.

Let me know if you need any additional info.
