Polyline is not drawn as closed after editing of "closed" flag via properties dialog.

Expected behavior

if "closed" flag is set in properties dialog, after closing properties dialog polyline should be drawn as closed one

Observed behavior

polyline still is drawn as not closed as soon as properties dialog is closed.

After forced redraw via menu - no still not closed. Zooming, panning - no effect. Modifying vertexes of the polyline - no effect.

If file is saved and reopened - proper closed polyline is drawn.

It does not matter, whether flag is checked or unchecked - it seems that proper drawing of polyline occurs only on next loading of the document.

Steps to reproduce or sample file

1. Select any polyline
2. Modify value of "closed" property (switch of state is needed)
3. Close the dialog
