1. Record some data with the QML Profiler.
2. Show the Timeline tab.
3. Zoom to a short duration at the end of the recording.
   I zoomed to ca. 20.80 to 20.84.
4. Make Creator's window more wide.
   At some point, the timeline will jump to a different time.
   Here it jumped to a time window from about 20.77 to 20.82. The time after that is not in sight anymore and I'd have to scroll to this time again.

After making the window more wide, the timeline should still display the same time window. It may display more than before but not less.
