    coverage: Enter correct compartment
    
    To use JS_GetGlobalForObject(), the context argument must be in the same
    compartment as the second argument. Since this call was part of another
    call entering that compartment, then the context was not already in that
    compartment, so the call triggers an assertion if mozjs is compiled with
    debug flags.
    
    Instead, we can use the second argument directly to indicate which
    compartment to enter.
