Flip cards stopped flipping?

Steve.B.446

Has anybody else noticed that Creator+ flip cards have lost the spinning animation in certain browsers? Clicking the card still goes to the other side, but instantly without the animation.

I haven't been able to narrow it down to being on specific browser versions (I have a slight unconfirmed suspicion that it could be a local policy only affecting browsers managed by our IT team) although I do note that there is a recent fixed issue about Flip Cards which might be implicated?
