Is [background-transition](https://revealjs.com/#/16) supported in Quarto?

Looking at the Quarto [Docs](https://quarto.org/docs/presentations/revealjs/#color-backgrounds) I did not find any reference to `background-transition`

I have tried the following but it does not work. 
```
## Slide Backgrounds {background="#43464B" background-transition="zoom"}
```
