# STEPS TO REPRODUCE
1. inspect any page
2. go to the Timelines Tab
3. select the Network Requests or Media & Animations timeline
  => the graph column has no content in the header
4. start a recording
  => the graph column header fills with content (if there are records for that timeline)
5. clear the recording
  => the graph content header goes blank again

I'm not sure what the expected behavior would be. It populates as soon as there is something to show, and without anything to show it's context-free.

I would expect the graph column header to have markers that match the time shown in the overview graph.  By default, the first 15s are selected in the overview, so we could show 15s worth of markers in the graph column header.
