In Internet Explorer 11, holding the mouse over a tag of a question used to bring up a tooltip with a short description of the tag. Now it only shows "Show questions tagged -tag-".

Where has this useful tooltip gone? Can we have it back in IE please?

    If I'm looking at a tag [foo] that is located under a question, and I point my mouse at the [foo] tag, I get the tag description. I only see what you're describing when I point at a tag that is in the right sidebar under "related tags". Commented Feb 8, 2018 at 12:54
  • I get it on the questions list page, e.g. stackoverflow.com/questions/tagged/c. I also get it on the question detail page. Commented Feb 8, 2018 at 13:00
  • Can't reproduce beyond my description on Chrome 64/Win7. Commented Feb 8, 2018 at 13:03
  • Also see what you describe under "favorite tags" in right sidebar. However, when I look at right sidebar under "Questions Tagged...", I get the tag description. Commented Feb 8, 2018 at 13:05

    I can repro on IE11/Win10. It looks like that an eventlistener didn't get registered. I can't verify yet if this is related but I doubt it is a coincidence.

    STOP THE PRESSES - reproduced in Win7/IE11. I suspect that it's an HTML5 feature that's not properly supported by IE, which is notorious for not conforming to standards. MS has decommitted from IE, and recommends using Windows 10 with Edge. Commented Feb 8, 2018 at 13:07
  • @JeffZeitlin, that is great. But they can hardly expect me to buy a new machine... But the tag tooltip worked fine. Has something changed on Stack Exchange? Commented Feb 8, 2018 at 13:14
  • has something changed ... yes, the site will get a responsive layout so a lot of stuff, both html structure as CSS, needs a major overhaul. So far the comment section has been un-tabled but I wouldn't be surprised if that already caused unwanted side-effects. One of which you might experience first hand right now.

  • It works fine in Chrome, Edge and Firefox (image), but I can reproduce it in Internet Explorer (image). Commented Feb 8, 2018 at 13:47
  • Can't reproduce on Edge. Commented Feb 8, 2018 at 13:48
  • @Ano well, Edge isn't IE... they finally made something different. Commented Feb 9, 2018 at 23:10

This will be fixed in the next build.

This was a slightly different manifestation of the same bug in Cannot start bounty using IE 11.

Right before the code executed that show user messages and wires up user menus, tag preferences, and keyboard shortcuts, we performed a check, if (CSS.supports). Unfortunately, not only does CSS.supports not exist in IE 11, neither does CSS, so we got an error checking a property on undefined.

  • From iOS to IE. Man, I don't envy you. Thanks for the fix! Commented Feb 13, 2018 at 22:42
  • Thanks Brian. Glad to get it back :-) Commented Feb 14, 2018 at 11:21
  • Solved! The tag tooltip is back. Many thanks! Commented Feb 15, 2018 at 13:22
