Large amounts of unicode modifiers stacked together result in white boxes on ubuntu

Reported by mason.os...@gmail.com, Aug 14 2017 
UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.90 Safari/537.36

Example URL:
http://www.eeemo.net/

Steps to reproduce the problem:
1. Look at text with lots of unicode modifiers like re͙̺͝p̡͈̯͇̤͎̥͇r̖̺̤͕̀ḛ̖̩͕s̡͈̮̼͇ͅe̹̠͇̹̪̼̯n̤̺͙̪t̻̤̘͇̮̝͠i̬̯̫̮ͅn̞g̛̤̟̯̖  in a webpage
2. see white boxes.
3. 

What is the expected behavior?
Garbled looking text.

What went wrong?
Stacking unicode characters in a document produces white boxes instead of stacked modifiers.

Does it occur on multiple sites: Yes

Is it a problem with a plugin? No 

Did this work before? N/A 

Does this work in other browsers? Yes

Chrome version: 60.0.3112.90  Channel: stable
OS Version: Ubuntu 16.04
Flash Version: 

It seems to only break on the linux version of chrome/chromium.

If you don't have fonts for them, you get whitebox.  That's expected.

Able to reproduce the issue on ubuntu 14.04 using chrome M60 #60.0.3112.90 and M62 #62.0.3187.0.

Issue is reproduced only in linux and not on windows and Mac os.

This is a non-regression issue seen from M47.

Thanks!

I don't think it's a system font problem, as the picture of it working is from firefox on the same computer.
