Steps to reproduce the problem:
1. Record a profile in the performance tab
2. Hover the mouse over the flame chart and scroll the mouse wheel

What is the expected behavior?
The flame chart should scroll down since the area is scrollable. 

What went wrong?
Instead of scrolling down, the view zooms out.  This feels weird since there is a scroll bar on the side of the panel that allows scrolling down.  I'm constantly messing up the view I've defined by trying to scroll down with the mouse wheel because I've forgotten that doesn't work.   I would expect the scroll wheel to to zoom the view in and out while hovering over the overview panel above the flame chart, but not on the flame chart itself.  

Did this work before? N/A 

Chrome version: 58.0.3029.110  Channel: stable
OS Version: OS X 10.11.6
Flash Version: Shockwave Flash 25.0 r0

After reading the documentation on this page it looks to me like this behavior may be quite intentional as it says  "To scroll a long flame chart in the Main section or any of its neighbors, click and hold while dragging up and down."   

https://developers.google.com/web/tools/chrome-devtools/evaluate-performance/reference#analyze

That certainly works, but it's quite unintuitive to click and drag to scroll when the standard behavior everywhere else is that the mouse wheel (or two fingers on the track pad) simply scrolls without clicking.  If this is currently working as intended I hope you'll consider changing it to match the behavior of other scrollable areas.  

Thanks,
