Linux Open File/Folder Dialog does not use set theme

[cavcrosby]

Type: Bug

1. Install/Use VSCode version 1.9x (noticed in 1.90, continues through 1.91) on a Linux distribution that has the GNOME desktop environment.
2. Open a file or folder in VSCode.
3. Observe that the file/folder dialog should use the default app theme.
4. Change the app theme to something different (e.g. via gnome-tweaks).
5. Open a file or folder in VSCode.
6. Observe that the file/folder dialog does not use the newly set theme.
