Hm...now you ignore the passed in options

if need defaults + passed in it should be:

init(instance) {
    setDefaults({ ...getDefaults(), ...instance.options.react});	    
    setI18n(instance);
  },
};

I seem setDefaults method merge options into defaultOptions.

export function setDefaults(options = {}) {
  defaultOptions = { ...defaultOptions, ...options };
}

right...i see now what you mean...the Trans component also takes stuff from i18nextOptions directly...for cases passed in i18n via props but using "setDefaults" does not change your options...

guess will merge options in Trans...please keep this open...will provide a fix asap

should be fixed in react-i18next@10.6.2
