Don't we need setter steps for this to update active types?

No, it's a readonly DOMTokenList. It stays constant, and you can mutate its internal token set with the DOMTokenList API

... made it readonly, that was indeed missing

Ah ok. So the attribute is readonly but you can mutate the DOMTokenList.

| 1. Let |viewTransition| be the result of running the [=method steps=] for {{Document/startViewTransition(updateCallback)}} given |updateCallback|. | ||

| 1. If |callbackOptions| is a {{StartViewTransitionOptions}}, then set |viewTransition|'s [=ViewTransition/active types=] to |callbackOptions|'s {{StartViewTransitionOptions/type}}. | ||
| 1. If |callbackOptions| is a {{StartViewTransitionOptions}}, then [=list/extend=] |viewTransition|'s [=ViewTransition/active types=] with |callbackOptions|'s {{StartViewTransitionOptions/type}}. |

nit: At every instance active types is updated, its value is overwritten completely instead of appending. Can we say that instead of extend to make that obvious?

It's the proper way to copy a list into an existing set (the token set). How would you reword it?

See revision, I'm setting it to the set from the rule when possible, but still using extend for adding the array from startViewTransition
