Thanks for reverting Reilly! Canary is super crashy because of this. Tried to track down why the crash and say your revert:)

Able to reproduce the issue on Win-10 using chrome reported version #70.0.3501.0.

Verified the fix on Win-10 using Chrome version #70.0.3501.2 as per the comment #0.
Attaching screen cast for reference.
Observed that Browser did not get crash after clicking on secure lock icon.
Hence, the fix is working as expected. 
Adding the verified labels.

Thanks...!!
