strict mode breaks Infusion components in Safari

Strict mode breaks Infusion components in Safari causing the following error to appear in the console. Disabling strict mode fixes this. Firefox and Chrome in Mac is fine.

[Error] TypeError: Attempted to assign to readonly property.

To reproduce:
1. Load any infusion demo (i.e. image reorderer or inline edit) in Safari
2. Notice you can't interact with the demo.
3. Remove / comment 'use strict' from Fluid.js
4. Reload demo in Safari - notice that the demo works.
