Description

Hello ppl, the ng-negative-number work only if you input the '-' char... but if you paste a negative number or change the ng-model to a negative value, it won´t work...

I am issuing this, because i need to change a money mask positive or negative acording to the dynamic calc of several fields... And thus can give me a ng-model positive or negative... but the field only gets the int and ignores the '-' from the model.

Research direction
Investigate the Angular input masks directive code that handles paste events and ng model updates. Look for how the minus sign is stripped or not handled when pasting or programmatically setting a negative value. Check the implementation of the mask parser and formatter to understand how negative numbers are processed. Consider adding logic to preserve the negative sign during paste and model changes.
