Description

If you call unwatch() on the return of watch() multiple times, it does a splice from -1:1 which removes arbitrary callbacks that it shouldn't. Test case and patch attached.

Presumably this is for Kris, unless it's really about dijit, but sounds like it's about Stateful.

Marking 1.8 blocker to get some eyes on this since unwatch on handles shouldn’t be destroying other handles. mbulman do you have a signed CLA?

In [28714]:

Add 'remove' method to Stateful.watch return handle to match handles from other methods, and fix the remove function so it does not destroy other handles when called more than once. Fixes #15364, #13282.
