Steps to reproduce

Every now and then I see Edge going off and constantly using 30%+ CPU on my Surface Pro 4. I used the Debug Diagnostics tool to do an analysis when it happened again just now. I have attached the results with the hope that it will be helpful to you. The offending website was Office365 Calendar and I couldn’t see much CPU activity in the JavaScript profiler. Unfortunately I forgot to capture that data before I killed the Edge process.
