Possible to suppress of annoying Chrome errors?

I'll often get errors in the output of Chrome. Here's a sample:

2018-07-08 13:13:20.143 Google Chrome[78169:25078696] *** Owner supplied to -[NSTrackingArea initWithRect:options:owner:userInfo:] referenced a deall
ocating object. Tracking area behavior is undefined. Break on NSTrackingAreaDeallocatingOwnerError to debug.

They clutter up my tests. Wondering if there is a known way to suppress them?

By the way, I tried the --disable-extensions launch_arg but it had no effect.
