The menu for Timeline > Keying > Active Keying Set wouldn't show up.

. The function to attach search menu data to the button
would be called twice with different arguments for the same button now.
Shouldn't be an issue in general, but the first call now had the unexpected
side effect that the button would get disabled. Make sure it's re-enabled when
the second call sets the proper search data now.
