Even though the ‘idea’ is closed, the community page still has issues scrolling when logged in. Community page not scrolling bug
When logged in I have custom scrollbar in the window. Scrolling (dragging, mousewheel) only works when I move the mouse over that custom scrollbar.
When I remove all cookies/storage and effectively logout I get the normal system scrollbar and scrolling works as expected again.
I experience this in the last 3 recent versions of desktop Safari.
