Sticky dynamic panel works in RP8 and doesn't in RP9. Events don't fire?

Hi, I have a file from RP 8 that contains a stick top that stays on the right side of the screen if you scroll down. If I resize the browser it always moves to the right position.

I switched to RP 9 now and it doesn’t work anymore. Is the onPageLoad and OnWindowResize Event bugged or are the adaptive views broken? I don’t get it.
