Pages at blog.skylined.nl render rediculously slow

Reported by skylined@chromium.org, Nov 15 2016 
UserAgent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:49.0) Gecko/20100101 Firefox/49.0

Steps to reproduce the problem:
1. Visit http://blog.skylined.nl/20161115001.html
2. Go make some coffee
3. Come back, wait for it finish rendering the page.

Added bonus: resize the window, go have dinner.

What is the expected behavior?
Should render fast like all other browsers

What went wrong?
Not sure where the hotspot is. But that should be easy to find out for any developer. If not, try BugId, it can detect high CPU usage and tell you in which function is probably the root cause.

Did this work before? N/A 

Does this work in other browsers? Yes

Chrome version: 56.0.2919.0 (Official Build) canary (64-bit)  Channel: canary
OS Version: 10.0
Flash Version: 24.0.0.154

Works fine in my Chrome 54 on Windows 7, might be a regression.

Thank you, I noticed that this issue only affects Chrome if you're running it with page heap enabled. I am assuming this is because the code is allocating and freeing a LOT of small memory blocks in order to render it. This issue should therefore not affect any real world scenario.

I apologize for wasting your time.
