Custom Issue Type Icon Not Showing in Issue Creation

Problem

When changing the issue type icon to a custom image, the custom image is displayed everywhere in JIRA (issue detail page and issue navigator) but not in Issue create screen. It shows the default or previous image. 

Steps to Reproduce

1. Go to Issue Types and change one of the issue types icon to a custom image.
2. Check in the issue navigator and issue detail page if the change have been picked up.
3. Create an issue and click the issue type dropdown.

Expected Result

The new custom image should show on the issue type dropdown during issue creation.

Actual Result

The old image shows rather than the custom one. 

Work-around

Restarting Jira after changing this icon appears to fix this problem.
Reindexing does not appear to have any effect
