Timeline_placeholder + addMarker work incorrectly

Gantt
#1

Hello! :wave:
As you can see here in this snippet use gantt.addMarker in combination with gantt.config.timeline_placeholder = true; in a gantt with a lot of task cause the marker don’t have full size of the gantt. How can I fix this? I espected the marker to be gantt full height.

Hello Rafael,
It is a bug in Gantt. The dev team will fix it in the future, but I cannot give you any ETA.

Now, as a workaround, you can increase the height via CSS:

.gantt_marker{
  height: 999999em !important;
}

Here is the snippet:
