Navigator blinking/jumping drawing objects test file

Similar to invisible sections causing blinking described in bug 118322, drawing
objects hidden by outline content folding cause blinking and jumping in the
Navigator.

Steps to repro in version 7.1 and above:

1) Enable experimental features Menu > Tools > Options or Alt + F12
Options dialog appears
2) In LibreOffice > Advanced tab Optional Features check 'Enable experimental
features (may be unstable)
3) In LibreOffice Writer > View tab check 'Show outline content visibility
button'
4) Open sidebar Navigator Menu > View > Sidebar and then select the Navigator
tab or F5 floating Navigator
5) Open attached example file 'DrawingObjectsTest.odt'

Results:
x11 vcl backend, Navigator content view blinks
gtk3 vcl backend, scrolled Navigator content view jumps back to selected entry

Expected results:
No blink and no jumping
