Mitigation Policy Flags (Image File Execution Options) are not applied to sandboxed images

[SSJPKXL]

Set Mitigation Policy Flags (Image File Execution Options) do not show up for sandboxed processes when policies are examined by Task Managers running with the highest (TrustedInstaller) privileges. Policies appear to apply, but it is hard to tell... If I set "DIsable Win32K Calls" policy for an executable image and that policy prevents that executable from running un-sandboxed, then that executable will also not run sandboxed. I don't know how to test if other policies are applied or not. Flags set by developers themselves for their executable images seem to show up, but again, it is hard to tell...

Set Image File Execution Options policies that do not show up for sandboxed processes are:
Control Flow Guard
ASLR - High Entropy
ASLR - Force Relocate
Heap Termination on Corruption
Dynamic Code Prohibition
Extension Point Disablement
Non-Microsoft Binary Block
Remote Load Disablement
Low Integrity Load Disablement

Side-question: Is it a bad idea to apply such policies for sandboxed processes?

Expected behavior

Mitigation Policy Flags (Image File Execution Options) should be showing for sandboxed processes
