Add comment on why you don't mark the intent as handled here (and below)?

The problem is ChromeTabbedActivity creates the tabs after this point, so if you
try to do anything with the current tab you might get some weird behavior.

For now until we start doing this for other activity types (which I don't see a
path where that would work), I would actually just add this in
ChromeTabbedActivity here:

https://cs.chromium.org/chromium/src/chrome/android/java/src/org/chromium/chr...

processUrlViewIntent is done when we are creating a new tab or doing something
on them.  It handles the saved instance state stuff for you, so I think that is
actually cleaner.

Ah I see. Okay moved it to processUrlViewIntent. This function is also called
from onNewNativeIntent (via mIntentHandler.onNewIntent), so we would only need
it in one place which is much cleaner (with the caveat that we're CCT won't get
this, but we're not supporting CCT anyway).
