Comment 1 Kai Uwe Broulik 2019-09-26 06:46:58 UTC 
According to Chromium source code this looks intentional:

  // Add the *.* filter, but only if we have added other filters (otherwise it
  // is implied). It needs to be added last to avoid being picked as the default
  // filter.
  if (file_types_.include_all_files && !file_types_.extensions.empty()) {
    DCHECK(filter_set.find("application/octet-stream") == filter_set.end());
    filter_vector.push_back("application/octet-stream");
  }
