ui.number event parameter value differs from object value properties

[CrystalWindSnake]

Question

# notify 0 when deleting value
ui.number(value=66, on_change=lambda e: ui.notify(f"{e.value=} {e.sender.value=}"))

When the input is cleared, e.value is 0 , expect it to be None . this is bug?

Thanks, @CrystalWindSnake!
Indeed, this looks like a bug somewhere in ui.number or even ValueElement. I'll create an issue from this discussion.
