This is really minor, but I think it might also be a one-liner:

Conditions:
You have opened a CCT in, e.g. Chrome dev
Chrome canary is set as your default browser

Current behavior:
"Open in Chrome canary" in the context menu opens a Herb tab

Expected behavior:
"Open in Chrome canary" opens a regular Chrome tab.

I think if you use setAlwaysUseBrowserUI (or add the equivalent extra) you should get normal tab treatment.
