[Admini]

thank you. if it is ok with you, please upstream the fix to the chromium project. all chromium-based browsers are affected by this bug.

We are not Chromium members. You can send this patch(content between "//add begin" and "//add end") to them:

Code:

    // Select the item saved in the pref.
    for (size_t i = 0; i < save_types_.size(); ++i) {
      if (save_types_[i] == preferred_save_type) {
        file_type_index = i;
        //add begin
        if (preferred_save_type == content::SAVE_PAGE_TYPE_AS_MHTML) {
          default_extension_copy = FILE_PATH_LITERAL("mhtml");
          suggested_path_copy = suggested_path_copy.ReplaceExtension(default_extension_copy);
        }
        //add end
        break;
      }
    }
