My impression was that `window.onerror` had a lot of special semantics behind it, e.g. censoring cross-domain stack traces on `Error` objects, determining the error message/URL/line number combination (sometimes), dealing with the return value of onerror, etc. See http://www.w3.org/html/wg/drafts/html/master/webappapis.html#runtime-script-errors and related.
