OpenFilePath directories are not enumerated within their parent folders

[antiufo]

Describe what you noticed and did

1. Create a new "Sandbox with Data Protection" (leaving all the default settings)
2. Outside the sandbox, mkdir C:\Test1 and mkdir C:\Test2
3. Sandbox options -> Resources -> Files -> Add C:\Test1 as "Normal" and C:\Test2 as "Open", save settings
4. Run cmd inside the sandbox
5. dir C:\

Actual outcome:

 Directory of C:\

2023-12-23  14:52    <DIR>          .
2023-12-23  14:52    <DIR>          ..
2023-12-23  14:52    <DIR>          Program Files
2023-12-23  14:52    <DIR>          Program Files (x86)
2023-12-23  14:50    <DIR>          Test1
2023-12-23  14:52    <DIR>          Users
2023-12-23  14:52    <DIR>          Windows
               0 File(s)              0 bytes
               7 Dir(s)  157,686,128,640 bytes free

Notice that only Test1 is visible, but not Test2.
Interestingly, if I cd C:\Test2, then I can use the folder as expected (creating a file inside the sandboxed cmd actually creates it in the real C:\Test2)

Additionally:
dir C:\Te* only displays Test1, whereas
dir C:\Te*2 successfully displays Test2.

I discovered this issue because some programs (understandably) fail to launch if they can't see and enumerate their own parent folders

How often did you encounter it so far?

I can reproduce it consistently

The same problem seems to exist with directives other than OpenFilePath. Only one item is enumerated per drive(?).
