The following errors are observer in the lists of hosts, items, triggers, item prototypes and trigger prototypes when attempting to execute Mass update action:

1. [DOM] Found 2 elements with non-unique id #ids_99131: (More info: https://goo.gl/9p2vKq) <input type=​"checkbox" id=​"ids_99131" name=​"ids[99131]​" value=​"99131" class=​"checkbox-radio">​
2. [DOM] Found 2 elements with non-unique id #context: (More info: https://goo.gl/9p2vKq) <input type=​"hidden" id=​"context" name=​"context" value=​"host">​

Steps to reproduce:

1. Open the list of hosts, items, triggers, trigger prototypes or item prototypes
2. Set the select all checkbox to true
3. Press "Mass update" button
4. Check browser console
