[regression] ComboBox inheritance not working

[Douglas Hays]

Beginning with [20738], ComboBox? is not working correctly. If you down arrow until More Choices and then TAB away, then the box value remains More choices instead of being reset to the last value. To recreate:
1) load dijit/tests/form/_autoComplete.html?testWidget=dijit.form.ComboBox?
2) find the box labeled "With option tags, autoComplete=true, pageSize=30, and a descending sort"
3) focus and down arrow until More choices is selected
4) press TAB
The value should revert to California but it stays More choices.
ComboBox? calls dijit.form.ValidationTextBox?.prototype._setValueAttr
which calls this.inherited(arguments) which no longer calls TextBox:_setValueAttr even though ValidationTextBox? inherits from TextBox?. This works fine in 1.3.2. Assigning to bill since I don't know if ComboBox? is doing inheritance incorrectly or if the new core changes to dojo.declare are broken.

Yes, I noted another breakage in #9862, I'm assuming it's a dojo.declare problem.

Related to #9862.

(In [20755]) dojo.declare: regression cleanup, !strict, fixes #10300, refs #9862.
