Jacek Caban (@jacek) commented about dlls/mshtml/htmlevent.c:
{ DOMProgressEvent *progress_event;
- if(compat_mode < COMPAT_MODE_IE10)
- if(compat_mode < COMPAT_MODE_IE10) {
nsIDOMProgressEvent_Release(iface);
Those constructors are just error-prone, I think it could be better to just move AddRefs to constructors.
