When I create new RadPanes and dock them to Left/Right/Top/Bottom the header isn't always set. I've attached a really simple project in which the issue can be reproduced.
1. Press "Add Main"
2. Press "Add Right"
3. Close right pane
4. Press "Add Right" - And the new RadPane has no header.
In our production application the issue is somewhat random, and I cannot see why it (almost always) fails. It almost seems like if a header has been set once on a certain pane, it is never set again on any new pane that is docked left/right.
However, If I make the pane float, the header is set, and docking it again retains the header.
