title: "Broad host permissions" Webstore warning despite only one host in permissions
body: <p>I'm trying to publish a chrome extension but, when I try, this message appears:</p>
  
  <blockquote>
    <p>Because of the following issue, your extension may require an in-depth review:</p>
    
    <ul>
    <li>Broad host permissions</li>
    </ul>
    
    <p>Instead of requesting broad host permissions, consider using the activeTab permission, or specify the sites that your extension needs access to. Both options are more secure than allowing full access to an indeterminate number of sites, and they may help minimize review times.</p>
    
    <p>The activeTab permission allows access to a tab in response to an explicit user gesture.</p>
  
  <pre><code>{
    ...
    "permissions": ["activeTab"]
  }
  </code></pre>
    
    <p>If your extension only needs to run on certain sites, simply specify those sites in the extension manifest:</p>
  
  <pre><code>{
    ...
    "permissions": ["https://example.com/*"]
  }
  </code></pre>
  </blockquote>
  
  <p>My manifest has those permissions:</p>
  
  <pre class="lang-js prettyprint-override"><code>{
   "manifest_version":2,
   "name": "Online Console",
   "version":"1.0",
  
   "description": "Simulador de consola de Online",
   "browser_action":{
    "default_icon": "icon24.png",
    "default_popup": "primero.html"
   },
   "permissions": [ "activeTab", "https://google.com" ], 
  
   "content_scripts": [{
      "js": [ "jquery.min.js" ],
      "matches": [ "http://*/*", "https://*/*" ]
   }]
  }
  </code></pre>
  
  <p>Why am I getting this warning and how to solve it?</p>
