For an example providing `NaN` to a css property will result in "_NaN is an invalid value for the fontSize css style property_".
Now I'm aware that there is an error in my code but I have no idea which component I should check.
I would like to have something like this: "_NaN is an invalid value for the fontSize style property. Check the render method of Header_".
I'll be happy to try to solve this if this is something we want to do.

warnStyleValueWithSemicolon(name, value);
    }
    if (typeof value === 'number' && isNaN(value)) {
      warnStyleValueIsNaN(name, value);
    }
  };
}
