This is a recent change since update 22, usually I am focusing on one part of an edit but then maybe i want to hit Enter to pre-render the red clips or I want to hit Render Audio to show my nested audio waveforms.
When the elements are rendered the sequence begins playing, so I would click the timeline marker back to where i am, which usually pauses the edit, bringing the marker back into my small focused area on the timeline.

However! since the recent 22 update, now this action throws me back to the beginning where the timeline has begun playing, taking me away from my focused area and causing me to have to find it again!

I clicked my timeline marker at 16min12, WHY AM I AT 0min3sec!???!!

I hope this explains my issue
