Animation of Textbox "By first Level Paragraph"

I'm trying to have a textbox animate four different topics one by one, and I have bullet points under some of the topics.  It looks something like this:

Topic 1

    bullet point 1

    bullet point 2

    bullet point 3

Topic 2

    bullet point 1

Topic 3

Topic  4

My expectation is the bullet points will animate with the topic if I choose the option "By first level paragraph" for the animation (since they are not "first level paragraphs").  This is how it would work in PowerPoint/Presenter. Unfortunately, they keep coming up one by one after the topic has animated.  Is this functionality not intended to work as I am expecting?
