Description Chris Dumez 2023-11-12 17:42:46 PST 
Use dynamicDowncast<T> even more in the DOM instead of is<T>() + downcast<T>(). It is less error-prone and often results in more concise code. I am also hoping to have downcast<>() do a type check on release builds in the future. It is currently too expensive to do so but it may become affordable if we use dynamicDowncast<T>() instead when possible.
