Comment (by adamsilverstein):

 [attachment:27485.2.patch] builds on [attachment:27485.patch] and
 completes IE8 compatibility for the Widget Customizer by swapping
 JavaScript indexOf (not supported for Arrays in IE8), instead using
 Underscore's  _.indexOf (which provides an IE8 fallback). Other than the
 order of passed variables, nothing else changes between indexOf and
 _.indexOf so I don't anticipate unexpected side effects.

 After applying this patch I no longer see console errors and I amble to
 add and remove widgets. One remaining IE8 issue is that when I click the
 Save & Publish button although the settings '''are saved''', the button
 does not update to the text 'Saved' as it does in other browsers. No
 console errors, just no change in the button. Digging more to see why that
 is.
