Javascript tag in view template makes details-module to disappear after submitting inline-editing in IE8

We have a customfield plugin which uses JavaScript generated by view template. And we faced with the problem which affects IE8 only. We have such problems while running JIRA 6.1-rc1, JIRA 6.1-rc2 and JIRA 6.1. But on JIRA 6.1-m5 everything works well.

<customfield-type key="fieldKey" class="com.fieldKey">
...
<resource type="velocity" name="view" location="templates/view.vm"/>
<resource type="velocity" name="edit" location="templates/edit.vm"/>
...
</customfield-type>

<script type="text/javascript"></script>

Environment:
JIRA 6.1-rc1 or JIRA 6.1-rc2 or v6.1#6144-sha1:2e50328,
IE8

Scenario:

• install plugin with above configuration
• create the customfield and put it to Default Screen
• create an issue
• navigate to view issue screen of the issue
• start inline-editing on any customfield in details-module
• submit editing
• see that details-module is gone
