Sorry, I should have been clearer in my original comments, but can we use the
enum here as well?

[whywhat, 2016/11/09 22:09:28]

Any advice on reusing the enum from public/platform/?

third_party/WebKit is not allowed in content/common or chrome/browser.
I bet content/common is not allowed in blink either.
