Can we pull this in soon?

Can this branch be merged, please? With these props, min={-100} max={100} strict, I can't enter a negative number by typing: "-50".

I did not see the fix in the version that I am using, which is:
"react-numeric-input": "^2.2.3"
i.e. the initial value is "0.0", then I am unable to enter "-1.0". The only way I can enter "-" is after I enter "1.0", then move cursor to front and add "-".
