JFXPanel ignores size change of root node

[Werner Lehmann]

Hi,

as far as I know JFXPanel is supposed to be sized according to its 
content (also stated in RT-13758). This does not seem to work when the 
content's size changes later: the jfxpanel is not resized along.

Hopefully I am missing something. The test code below creates a Swing 
flowlayout with a button, a jfxpanel, and a label:
http://s16.postimage.org/6nfil2myt/jfxpanel_width_160px.png

When clicking the button, the rectangle inside the fxpanel is resized 
from 160px to 120px width. The jfxpanel itself does not seem to be resized:
http://s16.postimage.org/p1q1p1z9h/jfxpanel_width_120px.png

It also does not work to increase the rectangle width - the jfxpanel 
width does not change. In my non-test application I have tried to remove 
and add the jfxpanel but that only works sometimes and is not exactly 
elegant. Any ideas?
