Where are these recorded?

[tsergeant, 2015/10/26 03:21:19]

Nowhere yet. The intention is replace
"ContentSettings.PermissionActions_<something>" with
"Permissions.Action.<something>" (discussed back in patchset 5).

[Ilya Sherman, 2015/10/29 00:20:15]

If these are not recorded, then let's not add them to histograms.xml.

[tsergeant, 2015/10/29 02:55:21]

Done.
