Windows Applications' Save As Dialogs don't Show the \Linux\ Folder

### Version

Microsoft Windows [Version 10.0.22621.674]

### WSL Version

- [X] WSL 2
- [ ] WSL 1

### Kernel Version

5.10.102.1

### Distro Version

Ubuntu 22.04

### Other Software

Visual Studio Code 1.72.2 with WSL extension
Notepad 11.2208.25.0

### Repro Steps

- ` ctrl-n` to create a new file in VS Code/Notepad
- Add content to new file
- `ctrl-s` to save new file

### Expected Behavior

- Application's save dialog should show the `\Linux\Ubuntu-22.04` (`\\wsl.localhost\Ubuntu-22.04`) folder in the same way as Windows File Explorer does

### Actual Behavior

- Application's save dialog _doesn't_ show the `\Linux\Ubuntu-22.04` (`\\wsl.localhost\Ubuntu-22.04`) folder

### Diagnostic Logs

_No response_

No repository file or test is named. Start by reproducing the Save As behavior in Visual Studio Code and Notepad on WSL 2 with Ubuntu 22.04, comparing their dialogs with Windows File Explorer; done means the \\wsl.localhost\\Ubuntu-22.04 folder is visible in those dialogs.
