Chrome 59+ websocket frames no longer visible in DevTools
The bottom "frame details panel" sometimes hides the "frames list" panel, unless you hover your mouse under a column header and drag down.
Update 1: As Sylvain Girard pointed out, this is Chromium issue 895548
Update 4: It's been fixed in Chrome 72, available in stable channel
Ugh, the UI was pulling the wool over my eyes. The pane that shows new frames was pulled all the way up so I could not see them.
It's a split pane with the frame summary on top, and individual frame inspector on bottom -- but the split divider was pulled all the way to the top. Was tough to see that. Google UI team: would be great to provide a better visual indicator on this :)
