leaflet: writer cursor does not appear after session idle

problem:
if shape was selected when document idle out,
on reconnecting cursor will not appear directly,
and after clicking somewhere cursor will not follow the view

the reason behind the problem:
if the shape was selected before idle out, on reconnecting
_clip._selectionType is not cleared and is still "complex"
this is what stops the view to follow cursor
cursor is not visible because _isCursorVisible never reset
