Jira application link and rendering Jira issue type icons not working with Jira macro

Jira version 6.3.15

Confluence and jira are accessible for users through reverse proxy with ssl termination. Additional connectors are created in tomcat config file to bypass ssl termination for application linking.

Applications links are created that application url is non-proxied url and display url is proxied-url. Links are working and its possible to insert Jira issues with Jira Macro in Confluence page. Only issue is that then inserting single Jira issues then Jira issue type icons are not rendered due to wrong urls in html:

<a href="https://jira.example.com/browse/GL-1" class="jira-issue-key"><img class="icon" src="http://10.0.0.1:8081/images/icons/issuetypes/subtask_alternate.png" />GL-1</a>

Intresting is that url in <a href=... is correct using display url
but <img class="icon" src=... is incorrect using application url

However urls to icons are working in page preview for single issues or if listing issues in table mode.
