Looks like #550 only made scrolling the preferences dialog tabs work (I can confirm that that still works) the tabs at the bottom of the sidepane still cannot be scrolled that way and in fact I don't see any code changes in the merged PR (in spite of its name) for the side pane. Only pluma-preferences-dialog.c was changed in that PR as it was merged, don't know if the side pane reuses some of that code. If so, that part is not working.
