How to make Premiere effect control marker not jump to next video (work like it used to)

Oh that's a great option that I disabled, thanks to you. But that isn't fixing the change. Let me provide step-by-step screenshots to reproduce the change that is causing me grief. To recap, the issue is that when I drag the marker in the effect control timeline to the end, it automatically jumps to the next clip. It never used to do that before.

1) select a clip and view the Effect Controls

2) Click the marker on the timeline in the Effects Control. Start draging the timeline toward the of the clip

3) When you reach the end of the timeline for the selected clip, it will jump clips over. Depending on how fast you drag, the more clips it will jump across. In this screenshot, it jumped 2 clips over 😞

You see, when the marker reaches the end, it used to stop and go no further. This allowed me to insert a keyframe at the very end of that clip. Now, when the marker reaches the end, it starts jumping clips as if it's working off the main timeline. I'm only working off the timeline of the selected clip in the effect control. I only expect to stay within that clip and not jump to the next.
