Alt + Scroll Wheel to Zoom in on Playhead in Timeline.
As mentioned in this thread https://forums.adobe.com/thread/2082047 when I use Alt+scroll wheel on mouse to zoom in my timeline, the playhead moves out of the area that has been zoomed into. That is to say that the playhead remains stationary at whatever time it was, but the area that is being zoomed into moves, generally (likely always) to later in the video. I spend a lot of time scroll back to find the playhead.
I am using windows 10 with a 4k display at 200% scaling. No amount of defaulting to 100% scaling, setting resolution to 1080 makes a difference.
In the above mentioned thread I am having the exact issue user Ferdinand83 is having and has shown in video proof. The question was marked answered by an Adobe staffer that obviously did not understand the question. It IS a bug, and it is a problem.
This is a MAJOR issue in workflow as it breaks concentration when zooming in to make a small edit.
