Anny Gakhokidze e12736fa36 Bug 1663238 - Only use the principal to inherit if it's equal to the flattened one, r=nika
With fission enabled, when we are starting a load, we might be saving
principals for a specific browsing context in process A, and then end up
targetting process B for the load, so during deserialization of the
LoadInfoArgs struct, we will end up using principals that were saved during a
previous load targetting that browsing context (with the same id) but in
process B.

Therefore, we cannot assert (without clearing the saved principals in the
original browsing context when a load is done, which can be done as a follow up
work) that the saved principal will be equal to the serialized one from
LoadInfoArgs.
