`this.el.val()` returns +null+ when previously set to and empty string, and `shallowEqualFuzzy` returns false when comparing null to '' which causes an infinite onChange callback loop. The new `fuzzyValuesEqual` method returns +true+ when `currentValue` is +null+ and `newValue` is equal to an empty string, otherwise it calls `shallowEqualFuzzy` which was the previous behavior.

When the
allowClearoption is enabled and that same component has aonChangecallback, clicking the clear icon will cause an infinite loop. The root cause seems to be thatthis.el.val()returnsnullwhen previously set to an empty string, which is what happens when the input is cleared. As expectedshallowEqualFuzzyreturnsfalsewhen comparingnullto''which causes an infiniteonChangecallback loop.The new
fuzzyValuesEqualmethod returnstruewhencurrentValueisnullandnewValueis equal to an empty string, otherwise it callsshallowEqualFuzzywhich was the previous behavior.I've also updated the examples with a select2 component set to
allowClearwhich can be used to manually test the new behavior. Let me know if there is anything you'd like me to change. Thanks! 😄
