Carousel has no stop/pause mechanism
A method MUST be provided to pause, stop, or hide any automatically updating content, or to manually control the timing of the updates.
Content that auto-updates - such as auto-advancing presentations and messages, and carousels, weather information, news, and stock prices - can be problematic for people who have trouble reading text quickly, people who have attention deficit disorders or other cognitive disabilities, and screen reader users. Auto-updating information must have an accessible mechanism to pause, stop, or hide it, or to control the timing of the updates. The ability to control auto-updating content allows people to consume information in a way that best suits their needs.
Fix this issue by providing an accessible mechanism to pause and restart carousel slides or to change the frequency with which the slides change.
