No-buttons appearance seems to have no effect on vertical selects

[nonorval]

Steps to recreate:
Render an XForm with a select field with appearance attribute set to "no-buttons" (without any columns specifier)

What I expect to see:
The radio buttons for the vertically oriented select are hidden.

What I see:
The radio buttons are still displayed.

I think the issue might relate to changes made a while ago for the columns styles and I have started working on a possible fix, but I wanted to check whether this is a known issue or what the intended behaviour might be.

Thanks! This was not a known issue. A PR would be great!

@MartijnR Sorry for the delayed response. I think I have a decent fix locally, just haven't gotten around to making a PR yet - things have been a bit busy this side. I'll make one in the next couple of days.
