Unable to type minus once right after blur/focus of controlled input

[insolite]

STR

1. Create and render controlled NumericInput component (using value/onChange and external state for example)
2. Focus on input
3. Clear value completely
4. Click outside input to lose focus
5. Focus on input again
6. Try to type -

ER

Input value becomes -

AR

Input value is unchanged (empty). The second press of - makes character appear though.

Conclusion

I guess there is something about NaN/null things in state. What really happens as I see:

1. On focus lose onBlur makes state.value become NaN (parseFloat("") => NaN)
2. When - is typed onChange is called and set state.value to null.
3. componentDidUpdate performs check for changed state, considers value changed (NaN !== null) and calls onChange callback (from props)
4. Parent component receives null value, passes it to the child NumericField.
5. NumericInput renders null as empty value.

There is a workaround for this: in parent component check if value was actually changed and only if so, rerender child (perform upper setState). But this will not fix another case:

1. Type any value like 123
2. Select entire value
3. Type -

The result here appear to be the same as for blur/focus case, so I consider this as a potential issue. Could someone help me?
