* STEPS TO REPRODUCE
1. Create a timeline recording with layout data on it
2. Go to Layout & Rendering timeline
3. Sort by duration by clicking on the heading

-> Exception!

It looks like the code in TimelineDataGrid._updatePopoverForSelectedNode() is pretty messed up. It uses `targetFrame` in a conditional before declaring it a dozen lines later. The conditional itself doesn't look correct either, so this code should be audited when this is looked at.
