showOpenDialog() returns object with path and fragment properties different from VS Code

[SamuelBergSTM]

Bug Description:

When selecting a file or folder using vscode.window.showOpenDialog(), fragments and paths are handled differently in Theia compared to VS Code.
Theia adds the part after the hash (#) to the fragment property of the vscode.Uri object, while VS Code appends it to the path property instead.

Steps to Reproduce:

1. Show a folder / file selector using vscode.window.showOpenDialog and await user response.
2. Select and open a folder / file path that includes a hash (#) (e.g. 'c:/example/#path').
3. Inspect the received vscode.Uri object properties.

Example:

const selectedUris = await vscode.window.showOpenDialog({ canSelectMany: false, canSelectFolders: true });
console.log(selectedUris?.[0]);

Additional Information

• Operating System: Windows 10 Enterprise
• Theia Version: 1.43.0

Theia vscode.Uri object path and fragment properties:
path: '/c:/example/'
fragment: 'path'

VS Code vscode.Uri object path and fragment properties:
path: '/C:/example/#path'
fragment: ''
