See https://dl.dropboxusercontent.com/u/27984093/tooltip.html

To reproduce:

  1. Hover over link, showing tooltip. Click the link.
  2. After landing on Google, press the browser's back button with a mouse. Keyboard shortcuts also work, but are slightly less consistent
  3. The tooltip now refuses to hide

Wow... that is weird... Apparently Safari and Firefox try to keep some kind of JS (and or HTML?) state. I'll try to figure out how to fix that... Seems like a very strange feature to me.

Thanks for the test page and the detailed bug report.

Yep, I noticed browsers starting to do that some time ago. A bit of googling turned up some interesting tidbits, this "frozen state" of the DOM and JS execution is called the "BFCache" (Back-forward cache):
