Issue Operations do not work properly in IE11

Summary:

any issue operations such as commenting or resolve/reopen issue using transition button for Service Desk enabled projects in IE 11 causes the browser to hang. After refreshing the page, user can see that the operation was actually successfully done (the comment gets posted, status gets changed, etc).

Steps to reproduce:

1. Open any issue in Service Desk Project (from agent's issue view page)
2. Perform any operation, lets say, click on Resolve issue button
3. Enter comment (optional)
4. Click on Resolve this issue button
5. JIRA will stay on that page, as shown below
   
6. Refresh the page (F5)
7. The status was actually changed to Resolved, and the comment got posted

Error thrown

Activating the developer tool shows

Unableto get property 'removeChild' of undefined or null reference
File: batch.js, Line: 139, Column: 394 

as shown in the screenshot below

Additional information:

Reproducible in IE 11 only
Does not happen with other version of IE and other browsers
