Description Thomas Schindl CLA 2015-02-24 17:53:31 EST 
Although it looks like this has been like this forever it makes no sense at all that CTabFolder layouts invisible children when someone calls layout(true,true) on a parent container.

Unfortunately CTabFolder is unable to intercept at the moment the updateLayout() recursion in Composite because this method is package protected nor does it allow to excluding children from the recursion.

The situation is getting even worse because of the new invalid behavior of CTabFolder which does such a force layout(true,true) on all siblings. See 460744
