Hi Wayne, Erich, and all, I think that authors can control whether or not they put important information in title attributes that are unreadable when cursors are enlarged. I have described the known issue [1]. Joanna Briggs from Simply Accessible wrote an article [2] regarding it. She states, "When hovering over a link that has a title attribute, the large mouse pointer covers the start of the title attribute. Longer title attributes may not fit inside the viewport with higher levels of magnification...In usability testing, we've even observed a user who was looking for a link on the screen. She didn’t know that she stopped her mouse over a link with a title attribute. That title attribute hid the link she was trying to hunt down. How do you avoid these problems? Just avoid using title attributes." The HTML5 Recommendation warns [3] against use of the title attribute. So WCAG 2.1 wouldn't be alone in calling out another title attribute issue. Alastair had suggested [4] that we could have a separate SC that stated: "Metadata in a webpage that is shown on mouse-over does not include information necessary to understanding the content or functionality." That may work, *if* we can figure out a way define "metadata". Or we could simply call out the issue by incorporating some more text and images regarding the problem into resize content (size of all elements) description [5].
