custom fontSize and text colors not correctly merged

[mhsfh]

Hello everyone,
i have similar problem to #178 but it's solution doesn't work for me
i customized font-size and colors in my tailwind config like this:

//...
colors: {
  white:"#fff",
  }
//...
fontSize: {
      button: ['18px'],
 }
//....

but i'm getting this conflict

console.log(twMerge('text-button text-white')); // => it return text-white

even tho i configured twMerge by siting the colors but i couldn't figure out how to configure font-size or font-family

const twMerge = extendTailwindMerge({
 theme: {
 colors:['white',...]
 },
});

thanks
