e.target vs e.currentTarget - TypeScript Knows the Type of currentTarget but Not target

e.currentTarget is typed as HTMLFormElement because it is always the element that registered the listener, while e.target is typed only as the generic EventTarget since the event may have bubbled from a child element - using e.currentTarget instead resolves the error

FormData's constructor does not accept any event property directly and always requires calling e.preventDefault() first before either target or currentTarget can be read

e.target is only available on native DOM events, not on React's SyntheticEvent wrapper, so accessing it at all is invalid regardless of typing

The fix is to cast e.target as HTMLFormElement, since currentTarget and target are functionally interchangeable in this scenario
