layoutNG busy loops renderer when visiting particular chat.google.com channel

Project Member Reported by wanderview@chromium.org, Today (13 hours ago) 
STR:

1. Open chrome canary desktop with layoutNG enabled.  I have (73.0.3680.0 on windows)
2. Visit chat.google.com.
3. Note that many channels render a bit janky.
4. Visit the "Blink Worker Team" channel.
5. Observe that the content loading progress bar starts animating, but then the tab freezes with chrome spinning a core.
6. Eventually chrome will open a dialog saying the renderer is not responding and ask if you want to kill it.

This problem does not reproduce if I manually disable layoutNG.

@kojii - We were having issues with:

white-space: pre-wrap;
word-wrap: break-word;

right?

chat.google.com seems to use this + things inside of a flexbox which are growing which probably causing this hang?

(I can profile if you like, but this seemed the same as the intrinsic size performance cliff).
