As well as ignoring scroll events on status elements when click_events is enabled. Previously, using the scroll wheel on a workspace button would switch to that workspace instead of scrolling through them. Clicks and scrolling on status elements would always be processed by swaybar, too. So in case you were using scrolling as volume control on a status item, swaybar would additionally scroll through your workspaces.
