I find this variable name weird given that it's the && of isPrivileged context
*with* the security state of the plugin URL. That is, the *context* is the
document (since ExecutionContext is a formal Blink term), and the context can be
privileged without the plugin being on a secure URL.

Can we come up with a better name that reflects this?
