TabPane / wrapped text

[Dirk Lemmermann]

Hi,

I noticed a difference in the way TabPane behaves when trying version 24.0.2 vs 
25-ea+28. It seems that TabPaneSkin.computePrefHeight(…) is no longer working 
as expected. This might be related to recent changes in the area of content 
bias and wrapped content. 

When you run the following test app you will notice that the window / the tab 
pane comes up with different heights depending on the version. In 25-ea+28 the 
window is not high enough and text gets cut off.

(The bug also exists in the 26 EA releases).

Regards,

Dirk
