Combo Box remote options mode erases tom select's load callback

[adanselm]

I'd like to combine remote options with the virtual scroll tom select plugin, which requires a custom load callback.
I can't do that because the combo-box-hook.js replaces this callback even if it's defined in my globalOpts:

    if (remoteOptionsEventName) {
      tomSelectOptions.load = (query, callback) => {
        const handleServerReply = (payload, ref) => {
          const resultsJSON = payload.results.map(({ text, value }) => ({
            text,
            value,
          }));

          callback(resultsJSON);
        };

Behaviour could be to not overwrite the callback if I defined my own in globalOpts and let me handle the complex loading on my own (if that's even possible in tom select to use both plugins at the same time).
