This is normal, whenever you click on a clip n the timeline, the effect controls panel's
timeline will stretch to the full length of the clip.
you can also right click on the clips containig keyframes on the editing timeline and
choose 'show clip keyframes', this way zooming the timeline will be the same for all.
If you have a large number of clips for which you want to reveal all keyframes and
edit them at once by selecting all or something, these are faster done inside After Effects,
or, submit a 'feature request'.
This would be something like add an animation timeline or improve the effect controls panel timeline.
