Can't resize template editor window in FF 27.0.1

• Type: Bug
• Status: Closed
• Resolution: Inactive
• Affects Version/s: 6.1.1 CE GA2
• Fix Version/s: 6.1.30 EE GA3
• Component/s: Content Display Widgets > Asset Publisher widget, ~[Archived] WCM > Publication
• Labels: None

Steps to reproduce issue:

1. fire up Liferay 6.1 CE Server
2. log in, using FF 27
3. add an asset publisher portlet
4. choose "Add New" > "Web Content"
5. click the configuration icon next to "Template: None"
6. fiddle around with resizing the popup window

The window got stuck in a state where I could not apply the resized view, and could not cancel it either (see attached screenshot). So far I could not reproduce this, will provide more information when I discover what exactly triggered the resize bug.
