Google Chrome	70.0.3505.0 (Official Build) canary (64-bit)
Firmware Version	Google_Eve.9584.160.0

I noticed after a powerwash and upgrade to Canary that the first time I used STS it crashed the browse. I was on a Wikipedia page. 

I then Powerwashed 3 more times and was unable to reproduce the bug.

Therefore, I am opening this bug and immediately closing it as WontFix just for tracking purposes in case this becomes reproducible.
