How to use ‘Align’ block setting in the markup template?

How can I use the values from the ‘Align’ setting on a block in its markup template? I would like to have them echo out as classes on the container. I tried {{align}} to no avail. Found this referenced in the docs which makes it look like this should be happening by default:

Thanks!
