Steps to reproduce the problem:
1. open url "chrome-devtools://devtools/bundled/inspector.html?experiments=true&v8only=true"

2. Switch to "Profile" Tab

3. Load a test.cpuprofile file

What is the expected behavior?
The flame chart should draw all the sample frame, chekcout excepted.png

What went wrong?
The max depth stack in the .cpuprofile file, the last frame doesn't draw in the main-view. checkout problem.png

Take a look the thumb-view, the second sample column is a bit higher than the first, but main-view draw as same height. There should be a "f6" frame in the second sample column.

Did this work before? N/A 

Chrome version: 58.0.3029.41  Channel: beta
OS Version: 4.10.8
Flash Version: 24.0.0.189

The test.cpuprofile is minimum data to reproduce the problem.

If a sample column is the max depth in all sample columns, and if it depth is bigger than 5, it's last frame won't be draw in main-view.

After hacking the devtools source code, I found how to workaround this.

The "5" constant variable is define here

https://chromium.googlesource.com/chromium/src/+/58.0.3029.41/third_party/WebKit/Source/devtools/front_end/profiler/CPUProfileView.js#352

So, if stack depth is less than 5, don't have this problem.

After change the line in

https://chromium.googlesource.com/chromium/src/+/58.0.3029.41/third_party/WebKit/Source/devtools/front_end/profiler/CPUProfileView.js#390

to "this._maxStackDepth = maxDepth + 1;", work as excepted.

That's because I found out "HeapProfile" has similar code, But it has "+1" for maxDepth variable.
