BTRFS "Size on disk > Details" does not work, while it should

reactos-bootcd-0.4.15-dev-5327-gc8ef276-x86-gcc-lin-dbg

Steps to reproduce:

• Install ReactOS on Btrfs
• Once on desktop, navigate to the root of disk C:
• Invoke context menu on "Documents and Settings" and select Properties
• Switch to the "Btrfs properties" page
• Click on "Details" hyperlink does nothing while it's supposed to open IDD_SIZE_DETAILS Dialog as per

and

Same in Windows XP (BTRFS 1.7.7) works fine :
