Thank you for This was a mistake. I fixed it.


BTW, what do you think which is preferable stepUp/Down for <input value=(empty/invalid) step="any" /> ?
- Not any changes after stepUp/Down.
  (e.g. step-up from renderer for <input type="number" value="foo" step="any" /> => "foo")
- Assuming value="0" or the current time, and no stepping due to step="any".
  (e.g. step-up from renderer for <input type="number" value="foo" step="any" /> => "0")

I think the latter is better to avoid invalid inputs.
In addition, the former looks complicating because value is sanitized out of stepUpFromRenderer().

FYI: The stepUp/Down DOM APIs for invalid values cause DOM Exceptions.
