There is currently a wildcard selector on .b-sch-event.b-sch-event-selected *. Setting font-weight: 500;
z-index: 6; on all descendant elements.
That makes it quite hard to handle custom react components for events. I currently have to use !important for font-weight and z-index in so many places which is not ideal.
Maybe this selector could be rewritten to only target events that are not using a custom eventRenderer.
