Comment 6 for bug 231477

This is a glitch with 'Flowed text' it seems. If I select the text object and convert it to text (menu 'Text > Convert to Text'), the stacking order of objects and layers is reflected on screen as expected (tested with Inkscpae r22115).

Or I can trigger to repaint the stack order of the objects on the screen by
1) change layer order (move 'text' to top)
2) select rectangle
3) move it aside to reveal the text
4) move it back to original position
5) text stays above rectangle
