[Bug]: Submit button time in intro/exit is only the time from when the button is displayed, not the whole page

[JamesPHoughton]

What happened?

If we want to use the submit button click time to tell us how long people take to complete an intro step, we can't take the start time from the point at which the button is rendered, because it may not be rendered until a condition is met, e.g. players have completed all the questions.
