Double apply transition

[maccman]

I'm seeing an issue that is causing a double toggle of the transition classes (even though show is continually true), ultimately resulting in a flash.

The issue looks like it's being caused by the initial variable changing, causing useIsoMorphicEffect to be re-triggered.

It goes like this:

1. First render of the component (initial = true)
2. Second render of the component (initial = false)

I'm curious why initial is a dependency on this useEffect?

useIsoMorphicEffect(() => {
    const node = container.current

    if (!node) return

    // Skipping initial transition
    if (initial && !appear) return

   ....
  }, [
    id,
    isTransitioning,
    unregister,
    nesting,
    container,
    initial,

Let me know if that doesn't make sense and I'll put together an example.
