Research direction
Open the example profile at https://share.firefox.dev/3jUOys0 and reproduce selecting a range over the timeline on the Firefox Profiler web app. No source files or tests are named; investigate the timeline selection and preview behavior, then verify that the preview follows the mouse smoothly on a long profile.
