63672 - JS strict warnings execute onerror handlers...

Status: VERIFIED DUPLICATE of bug 220603

(Core :: DOM: Core & HTML, defect, P2)

Description

[Johnny Stenback (:jst)]

Even if a page contains JS strict warnings the onerror handler should not be
called. onerror is for *errors*, not for warnings.

This patch makes mozilla not call the onerror handler for JS strict warnings:

Ok, turns out this is an invalid bug, if you want JS warnings to be treated as
errors then they will call the onerror handler.
