One challenge I've had with window.onerror is catching the errors in another window (or iframe), since it's not possible to attach an onerror handler before the window content loads (because it is overwritten when the window content loads). The result is that the parent window cannot catch errors in the child window without the child window opting into it, by setting `window.onerror = window.parent.onerror`. If window.onerror and a possble window.onPromiseCatch is to be standardized then it should be possible for one window to handle the errors in child windows (taking same origin and CSP into consideration ofcourse). This should probably be generalized to realms, so that one realm can catch all the errors in another realm. Marius Gundersen
