Done.

One question: Do you know how to take care of this Closure error?

##
/media/largedrive/code/chromium/src/chrome/browser/resources/settings/site_settings/site_details_permission.js:69:
ERROR - Property setting never defined on originPref
##     if (originPref.setting == settings.DefaultValues.ALLOW) {
##                    ^

[michaelpg, 2015/11/09 18:26:30]

Ultimately you'll need to annotate the type of originPref for Closure so it
knows it has a "setting" property of type {number}. Or just use
originPref['setting'] if you'd rather not typedef it.

[michaelpg, 2015/11/09 18:26:30]

hmm, kinda wish we had named this something more specific,
"settings.DefaultValues" is a weird name for something specific to content
settings

[Finnur, 2015/11/10 16:00:51]

I agree. Renamed.

[Finnur, 2015/11/10 16:00:51]

For some reason I was stuck in the mindset of having to define a struct with
types somewhere, when instead I can just add the Closure directive right there.

+      this.$.permission.selected = 0;
+      this.$.details.hidden = false;
+    } else if (originPref.setting == settings.DefaultValues.BLOCK) {
+      this.$.permission.selected = 1;
+      this.$.details.hidden = false;
+    }
+  },
+
+  resetPermission: function() {
+    var pref = this.getPref(
+        this.computeCategoryExceptionsPrefName(this.category));
+    delete pref.value[this.origin + ',' + this.origin];
+    delete pref.value[this.origin + ',*'];
+    this.setPrefValue(
+        this.computeCategoryExceptionsPrefName(this.category), pref.value);
+    this.$.details.hidden = true;
+  },
+});
