WSL - sshfs-mounted directories appear empty in VS Code Explorer

Type: Bug

Description:
When connecting to WSL using the WSL extension and opening a directory that contains an sshfs mount, VS Code’s Explorer shows the directory as empty, even though files and subdirectories are visible from the WSL terminal.

Expected behavior:
Files and directories inside an sshfs-mounted path should be visible and accessible in VS Code Explorer, the same way they are when listed from the WSL terminal.

Actual behavior:
VS Code Explorer shows no files or folders in the mounted directory.
The same path shows correct contents when listed in the WSL terminal (ls).

Comparison with Remote - SSH:
If I connect to the same WSL instance using VS Code’s Remote - SSH extension (connecting to WSL over SSH) and open the same path, the files and directories inside the sshfs mount are visible and work as expected.

Mount command used:
sshfs -o allow_other,reconnect,uid=$(id -u),gid=$(id -g) someuser@example-host.com:/ /mnt/example

Steps to reproduce:

1)Inside WSL, mount a remote filesystem using sshfs:
sshfs -o allow_other,reconnect,uid=$(id -u),gid=$(id -g) someuser@example-host.com:/ /mnt/example

2)Verify in the WSL terminal that /mnt/example contains files and directories.

3)Open VS Code and connect using WSL extension.

4)Open /mnt/example in VS Code Explorer.

5)Observe that the directory appears empty.

6)Connect to the same WSL instance using Remote - SSH instead and open /mnt/example.

7)Observe that files and directories are visible in this case.

Environment:
OS (runs VS Code): Windows 11 25H2 build 26200.7623
VS Code: 1.108.1
WSL extension: 0.104.3
Remote - SSH extension: 0.122.0
WSL distro version: WSL2 Ubuntu 24.04 (Linux rhsCZ-wsl 6.6.87.2-microsoft-standard-WSL2 #1 SMP PREEMPT_DYNAMIC Thu Jun 5 18:30:46 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux)

Notes:
This suggests a difference in how WSL extension and Remote - SSH extension handle FUSE/sshfs-mounted filesystems, even when both ultimately access the same WSL environment.
