In Bug 201597, we added new features to better lock down JSC features in the potentially untrusted WebContent process.
Unfortunately, this change included XPC Dictionary items used at startup to lock down JSC features before entering the main execution of the process. These changes were not done for the WinCairo or FTW ports.
We need to pass the state of the JIT and whether to enable certain JSC features at process launch. Since the XPC mechanisms we use on macOS and iOS do not exist on Windows, I am implementing them as command-line flags.
