Symptoms

When saving an asset in Contributor UI, there is a warning that pops up due to a javascript error:

Warning: Unresponsive Script - A script on this page may be busy, or it may have stopped responding. You can stop the script now, open the script in the debugger, or let the script continue.
Script: http://host:port/context/js/dojo/dojo.js:14
(OR) http://host:port/context/js/fw/fw_ui.js:9

When this error pops up, the whole Web center Sites UI freezes and cannot proceed until the user clicks 'Stop Script'.

With the uncompressed js files, the error could be coming from:

http://host:port/context/js/dojo/dojo.js:7045

http://host:port/context/js/dojo/dojo.js:2354

http://host:port/context/js/fw/fw_ui.js:2520

Changes

UI/Layout/LeftNavigationConfig has been customized with showParentsOnly set to false for Content Tree and Site Tree.
