Focus is not managed appropriately. When selecting the proceed button focus stays on the button and no information is conveyed to screen reader users that anything has occurred.
When the question dialog is displayed focus is placed on the first answer to the question. This
leads to confusion and forces screen reader users to perform additional steps to find out what
the question is.
1. Move focus when proceeding to next "slide".
2. Make sure focus is moved to the entire question when branching, not just the first alternative. (See how Multiple Choice does it.)
