Needs Accessibility Improvements

I really like the way this plugin approaches popup management and display. Unfortunately, I have a hard time justifying its use due to some fairly critical accessibility issues. I would love it and sing this plugin’s praises if it weren’t just easy to use but also notably accessible!

So far, I’ve run into these issues with only a cursory amount of poking and prodding:

• Close button is a div, not a button
• Close button has no accessible label, it’s just empty with an empty <i> element for the icon which needs aria-hidden
• The “open chat” button has the same issues as the close button
• Popups should force keyboard focus to the first focusable element in the popup and then “trap” focus within the popup until close. (I’m not totally sure what the correct focus management is for the “chat”-style popups.)
• ESC should close popups
