This seems to happen to folders created by the webdav client only.

when trying to bookmark a folder in the media section, clicking on the folder that got created via the webdav client takes the left hand navigation back to the content section (content tab gets highlighted) although the url remains correct (http://hostname/media/images/bla. The centre column also remains correct

Steps to reproduce

login to the webdav client and create a folder called tmp under /media/images
close the webdav client
login to the admin siteaccess
click on the media tab
click on /images/tmp

the left hand nav switches to the content tab although the url and the centre column remain correct
