This was done per Grace's comment:

I couldn't think of a reason for suspending prior to it navigating. What happens
if you also get a resume before the webview is navigated? Presumably both
messages are queue and it sitll works?

-        host->AddObserver(this);
-        host->Send(new ViewMsg_SetWebKitSharedTimersSuspended(true));
-        suspended_processes_.push_back(host->GetID());
-      }
+      host->AddObserver(this);
+      host->Send(new ViewMsg_SetWebKitSharedTimersSuspended(true));
+      suspended_processes_.push_back(host->GetID());
     }
   }
 
   // Resumes timers in processes that were previously stopped.
   void ResumeWebkitSharedTimers() {
     for (std::vector<int>::const_iterator it = suspended_processes_.begin();
          it != suspended_processes_.end(); ++it) {
       content::RenderProcessHost* host =
           content::RenderProcessHost::FromID(*it);
       DCHECK(host);
