case DISPID_EXTERNAL_GETMIMETYPE: ``` And it still expects `DISPATCH_PROPERTYGET | DISPATCH_METHOD`. So I guess it will be postponed due to code freeze. After wasting time on a dead end solution, actually I realized it's easier than I thought, since the issue was just cross-context script objects. For those we can still just not add PROPERTYGET, as long as they're still a jsdisp.
