How is this possible? I thought favicons were static ICO files, incapable of animation?

It turns out that animated favicons are actually possible, and some websites have them: see How to disable animated favicons?.
But this particular instance wasn't caused by the Stack Exchange website; it turned out that I have a userscript for that page in Violentmonkey, which (in the background) performs HTTP calls to the Help Center of each website in the list. Somehow (I don't know the exact details) the favicons of those websites get loaded as well and are applied to the Firefox tab, causing an animation. The last call is to Stack Overflow so that icon remains as a final state.
If you want to experience it yourself, you can install of the most popular userscripts for Stack Exchange: Global Flag Summary – it displays this behaviour as well. I'm not exactly sure in which setups (userscript manager/browser/operating system) this works, but I'm running Violentmonkey v2.11.2 in Firefox 69.0.1 on macOS 10.14.6.

For most browsers, favicons are static image files, but websites can take advantage of JavaScript to modify the current favicon shown, effectively animating it. Firefox also allows GIF type favicons and plays the animation accordingly.
