clone(true) creates bogus event bindings if you extend Array.prototype

Reported by: airportyh Owned by: dmethvin
Priority: high Milestone: 1.5
Component: manipulation Version: 1.4.3
Keywords: Cc:
Blocked by: Blocking:

If you added extra methods to Array.prototype and use jQuery.clone(true) to clone an element which has bound events,

it will create bogus event bindings: one for each extra method you added to Array.prototype. The test added to test/unit/manipulation.js

demonstrates this.

+1. Just discovered this bug today on a site we're upgrading to 1.4.2. This did not happen under 1.3.2. It's in the cloneCopyEvent method, and affects IE.

Seeing as this has already got a quality patch with an adequate test, it should be easy enough to integrate?
