Bug in FF when FCKConfig.StartupShowBlocks=true on a hidden FCKEditor instance

Error in Firebug (under FF3):

FCK.EditorWindow.getSelection() is null [Break on this error] var FCKShowBlockCommand=function(A,B){th...e()!=this._SavedState) this.Execute();};

Error fckeditorcode_gecko.js line 71.

Apparently FCKEditor needs to work on visible elements to apply "show block" on startup.

Confirmed in Mozilla 3 and Safari (Vista32). In IE works fine.

FCKeditor was retired and is no longer supported. All active development was moved to its successor, ​CKEditor 3.x, that is a fully mature and far superior product. We recommend you upgrade as soon as possible since this issue is no longer a problem in current code base.

This works in CKEditor.
