1. Open attachment 185791 [details] then look at the new Accessibility sidebar, listing a lot of issues.
2. Try to scroll the list with the mouse wheel
-> There is only about 1 line up/down movement. You need to use the vertical scroll bar to see the bottom of the list.

Seems to work fine under GTK3 vcl.
Likely a side effect from the dialog->sidebar conversion in bug 142978.
