I can't open the attached testcase - the default Ubuntu Archive Manager claims the archive is invalid.

As such, I'm marking the issue as INVALID.  If there is still a problem, please reopen the bug with a testcase illustrating the problem.

same test case as zip

The attached archive decompresses without any problem for me. Attaching .zip.

I suspect that we just don't support .ani cursors in CoreGraphics (and likely not in either ports either).

Thanks, Alexey!

Yup, confirmed that we don't support .ANI files in Windows Chrome either.  In that case, marking this as NEW and changing the the title.

Note that IE supports ANI files in 'cursor'.  Firefox explicitly does not, according to MDN.

Only Internet Explorer supported ANI format and Mozilla also marked their bug as RESOLVED WONTFIX - https://bugzilla.mozilla.org/show_bug.cgi?id=434319

Chrome never added support even after change to Blink. So I think no major browser as of today support it and there are even articles about how to do it via JavaScript - https://stackoverflow.com/questions/9189250/animated-cursor-support-in-web-applications & https://dev.to/chris_hayes/make-a-gif-your-cursor-in-chrome-4odo

I think we can mark this as "RESOLVED WONTFIX" unless Webkit has future plans. Thanks!

Yeah, this is won't fix at this point.
