I see that the bug is specific to Cookies, but this edit feature was present in
other sections (other than cookies) in the old options. Can we make this match
that? Or at a minimum, add a TODO here and a crbug saying that this feature
needs to be expanded to the other content settings.

Done, https://bugs.chromium.org/p/chromium/issues/detail?id=695578.
