Currently, HTMLInputElement::setValueAsNumber throws NOT_SUPPORTED_ERR if newValue is infinity. This behavior is wrong because infinity is a valid number. Each input type additionally checks if the number is infinity or not. For example, NumberInputType::setValueAsDouble compares newValue to +floatMax and -floatMax and throws INVALID_STATE_ERR. Changed HTMLInputElement::setValueAsNumber to check isnan(newValue) instead of !isfinite(newValue).

Oops. I found the following note from the HTML5 spec: The Infinity and Not-a-Number (NaN) values are not valid floating-point numbers.
