nit: have a comment here for overriding methods

// PerformanceResourceTiming overrides:

[sunjian, 2016/11/11 21:48:05]

Done.

Can we omit this field by using PerformanceResourceTiming::m_allowTimingDetails?

[panicker, 2016/11/11 17:14:02]

This is a bit different from allowTimingDetails which comes from the TAO opt-in
for given resource, we don't need TAO opt-in on the document resource.
 "m_allowRedirectDetails" is also not the right counterpart, here we want an
indicator for "cross-origin redirects were involved when navigating to the
document" I think.

Acknowledged.
