We do limit the timeline window by default -- this is done primarily to avoid updating main window and hence reduce resource contention to the inspected page (it can be pretty bad occasionally -- in particular, on chromium mac this causes animation frame rate to degrade from 60fps to 30fps if DevTools are docked to the inspected window, as browser window updates are apparently v-synced).

So the behavior that you describe sounds as "by design" to me. We could probably improve the usability slightly by making the window more explicit. Are you using Events or Frame mode? Historically, selected window is visualized a bit subtle in Events mode, so I guess this may be the source of confusion.
