Activating a timeline marker causes screen reader to read entire text contents of slide.	Enhancement	Identified	Screen reader	<div class="tl-slider-container tlanimate" aria-live="polite">	Reading the entire contents of a slide when it comes into view is too much at once and it might get interrupted by other interactions.Maybe read just the heading and let user navigate to the slide to navigate the contents as they like.
