Do alkenes have priority over alkynes in R/S naming?

I am studying for an upcoming exam and I came upon a confusing question for the drawing of the molecule (3⁠*R*)-hex-1-en-5-yn-3-ol.


[![(3R)-hex-1-en-5-yn-3-ol](https://i.stack.imgur.com/vwRjK.png)](https://i.stack.imgur.com/vwRjK.png)


Why is the stereocenter (3-carbon) R? Shouldn't it be S? After looking at it, I see that the priority is OH > alkyne > alkene. I'm really confused.
