As a workaround solution, add this custom CSS to Appearance > Customize > Additional CSS to get a scrollbar to the bottom of the timeline:
@media (min-width:1024px){
.timeline-area.horizantal-timeline {
width: 1000px;
overflow-x: scroll;
display: block;
white-space: nowrap
}
.ekit-wid-con .horizantal-timeline .single-timeline {
width: 25% !important;
display: inline-block;
white-space: wrap
}
}
After applying this CSS, you will be able to see the timeline with the scrollbar (demo video).
