Thai characters cannot be rendered properly sometimes

Reported by rocker1...@gmail.com, Jun 6 2018

Issue description

UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.62 Safari/537.36

Example URL:
data:text/html,<meta charset="utf-8"><p>%E2%9C%BA%E2%97%9F(%E2%88%97%E2%9D%9B%E0%B8%B1%E1%B4%97%E2%9D%9B%E0%B8%B1%E2%88%97)%E2%97%9E%E2%9C%BA<p>a%E2%9C%BA%E2%97%9F(%E2%88%97%E2%9D%9B%E0%B8%B1%E1%B4%97%E2%9D%9B%E0%B8%B1%E2%88%97)%E2%97%9E%E2%9C%BA

Steps to reproduce the problem:
1. open any webpage contains character "✺◟(∗❛ัᴗ❛ั∗)◞✺"
2. try add an "a" before it, for example "a✺◟(∗❛ัᴗ❛ั∗)◞✺"
3. Ironically, it works "just fine" in the location bar (see attachment)

What is the expected behavior?
It should be rendered as a✺◟(∗❛ัᴗ❛ั∗)◞✺ (without leading "a").

What went wrong?
It cannot be rendered properly without that leading latin character.

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: 67.0.3396.62  Channel: stable
OS Version: 4.16.13-2-ARCH
Flash Version: Not Installed

Chrome 67 on Android/Windows/macOS also have this problem.

Works fine for me on a Debian based machine with 67.0.3396.62 but not on a MacOS machine.
