Currently, the pop-up and slide-in do not take keyboard focus when they are opened. A keyboard user has to search for a way to get into the dialog to close it or take action. This is not good for accessibility and WCAG guidelines. Requesting to have the dialogs take keyboard focus to so the user can tab through with ease. Adding a tabindex to a container div along with giving that container the focus is an easy enough integration to satisfy this very important accessible feature.
