File dialog loads slowly when using defaultPath

[mmichilot]

Description

When using FileDialog.getOpenFiles with the defaultPath option, it takes a while (~10 seconds) to load the file list. However, when it's manually refreshed, the file list loads immediately.

When defaultPath is not given, the file list is loaded immediately, however this limits the file dialog to starting from the root folder.

Reproduce

Create a file dialog with FileDialog.getOpenFiles and pass a defaultPath option.

Expected behavior

I would've expected the file list the to load once the dialog opened, especially since manually refreshing works immediately.

Context

• Browser and version: Firefox 119
• JupyterLab version: 4.1.0a3

It sounds like it could be that it does not take 10s but you see it auto-refresh every 10s. So maybe the initial reply is not handled correctly to populate the contents or maybe there is just a missing update after the initial response was received.
