I have had feedback from users, which I am inclined to agree with, that the hovercard that appears when you hover over a topic title takes far too long to dismiss when you move your mouse out. It currently takes 3 seconds [citation needed], but I think 1 second would be more appropriate, and if you click outside the card it should dismiss almost immediately.

Just change

data-ipsHover-timeout='1.5'

to whatever.
