Call Stack Expanding: Summary

When debugging node.js via devtools and --inspect, the devtools "Call Stack" accordian panel expands automatically, forcing the "Scope" panel out of the viewable area.

Versions

• macOS 10.13
• node v6.11.4, node v6.11.3
• Chrome 62.0.3202.62, Chrome 61.0.3163.100

Steps to reproduce

• Launch a simple test program with node --inspect --debug-brk

console.log("Collapse the call stack panel at program start");
setTimeout(() => {
  console.log("Set a breakpoint on this line");
}, 1000);

• In devtools, set a breakpoint for code not yet hit
• collapse the "Call Stack" panel
• Click Play
• When the breakpoint is hit, the "Call Stack" panel expands automatically
