Setting a New Focus

Hi, we're working on making our product accessible, and I've run into a problem that I don't know if there is a fix for. I've attached the file so you can see.

In slide 1.9 we have the tab order set up the way we want with the title first, and while this usually works, for this slide in particular, the tab order starts on the text field. My guess is that it has something to do with the triggers calling up the student's essay response when the timeline starts, but I don't know what to do about it.

Can anyone figure out how to fix this so that the text field doesn't grab focus away from the title when the timeline starts? Thanks!
