Timeline with many resources cannot see times

We’ve noticed that when we have a timeline view with very many resources, such that you need to scroll down the page, the times along the top are no longer visible. Is there any solution to this, like a floating header or even just periodically adding a row with the times listed?

vertical scrollbar appears if you limit height of scheduler container, please check the example

However, there is no easy way to achieve this if you use container_autoresize extension
