TYPO3 Core

Upon click in the list-frame of the filelist-Module, the list view for that folder is displayed, and in the browser console following error appears:

13:45:52.448 SEVERE - http://localhost:8000/typo3temp/var/tests/acceptance/typo3/index.php?route=%2Ffile%2FFilelistList%2F&token=cb5fdd3e7678f271f54a75f5a0aacb641fc38e18&target=1%253A%252F&imagemode=1 263:461 Uncaught TypeError: Cannot read property 'contentWindow' of undefined

This onclick event should update the position in the folder tree, but fails.

BTW, in list view, no error is displayed, and also the selected page position is not highlighted in page tree. Maybe this is just a forgotten bit of code left from the svg tree switch?
The offending code is located in ext:filelist/Classes/Filelist::linkWrapDir().
