ReferenceError: setImmediate is not defined

[krnlde]

Describe the bug
When trying to call the callback method provided by read in a plugin, the error ReferenceError: setImmediate is not defined is thrown into the console.

setImmediate() is a non-standard API and shouldn't be used in frontend code.

Occurs in react-i18next version
Occurs in the latest version of react-i18next which is currently v10.5.0.

Additional context
We use a custom backend-plugin as described here, which eventually calls the callback from the read property like here:

// ...
read: function(language, namespace, callback) {
    /* return resources */
    callback(null, {
      key: 'value'
    });
  },
// ...

replaced with a setTimeout(()=>(),0) in react-i18next@10.5.1
