Trackpad gestures handled on the marker chart should also work on the timeline

While hovering the marker chart, I can pinch-zoom to select a narrower area, or horizontal scroll to change the selected area.

It would be nice to have these gestures also work when hovering the timeline. Currently pinch-zooming there zooms the entire page, which is generally not very useful on the profiler, and horizontal scrolling doesn't work (but would be really handle when hovering the power track, to compare the power use of a selected active area with the power use of an inactive area of exactly the same duration).
