[TYPO3-core] RFC: #8092: defect wsid check in workspace-overlay delivering wrong record versions from DB!

if it's omitted, then it will be set to $GLOBALS['BE_USER']->workspace 
which should contain something - but it doesn't as I found out. I just 
did a debug on $GLOBALS['BE_USER']->workspace in the method 
'workspaceOL' - and it's EMPTY/NULL during the first X calls to the 
method when I f.e. save a record - where "X" is the level depth of the 
page in rootline. So there is somewhere a rootline check before 
workspaces are initiated.

But know I'm out of any ideas where this could come from. Hope some of 
the core DEVs might have an idea.
