When using Vertical Grouping by multiple resources and Timeline View, the group rows without appointments do not have min-height as the rest of the group rows. Thus, they appear shorter which causes an offset of the events on the next rows.

Steps to reproduce:

1. Load Timeline View Demo
2. Delete Charlie's event in Small meeting room

A possible workaround for the time being is to set min-height to all rows. Apply this style only when Timeline view is selected, so this does not break the rendering of the other views.
