I think so. It looks a bug of the current code.

The failure was:
@@ -15,7 +15,7 @@
 PASS changeEventCounter is 0
 PASS inputEventCounter is 1
 Focus on another field
-PASS changeEventCounter is 1
+FAIL changeEventCounter should be 1. Was 0.
 PASS inputEventCounter is 1
 PASS successfullyParsed is true

'change' was not fired when the number input lost focus after updating the value by the spin button.
HTMLInputElement::stepUpFromRenderer() uses setValueAsNumber() internally. So m_wasModifiedByUser and m_textAsOfLastFormControlChangeEvent are always reset.

Yeah, I completely overlooked this failure. New patch fixes this issue by propagating sendChangeEvent through various functions from stepUpFromRenderer.
