I am getting the following WCAG error when using the plugin

This button element does not have a name available to an accessibility API. Valid names are: title attribute, element content.

Is there a way to pass a title for the up / down buttons?

I tried to use buttondown_txt property but it's ignored if you are using verticalbuttons: true ...
